I am sorry your wife is having so many problems, but it sounds like the worst ones are treatable and can be resolved.
The diarrhea (and even soft stools) can be a big problem but she will feel much better (and so will her butt) if she can firm up those stools, quite form, not like rocks, but really quite firm. I took Loperimide (Immodium) as needed. Once I got them under control, I did not need it every day, but at the second I got a soft or loose stooll I took it. Loperimide is over the counter.
For the nausea I took Zofran. I took and still take Zofran 8 mg every 8 hours. It works miracles (for me anyway) and the nausea is under control. I had gotten to the point where I could barely eat anything and the nausea snowballed into other problems. I should have been on Zofran from about week 2 but I did not know anything then, lol. Ask the doctor for a prescription for Zofran every 8 hours (get a high enough dose) and then take it on schedule every 8 hours. It works best if taken before one gets nauseated and then it prevents the nausea. But it wil also work if one is already nauseated. I think getting the nausea under control is imperative. Not only will she be able to eat, but she will also feel better physiologically.
Hopefully the doc will order the med, but you may have to be insistant, I had to be quite insistant.
You don't say how bad her skin rash is and if she is itching. If she has a rash taht is more than a few bumps and/or she has itching that problem needs to be delat with. The rash can really snowball and get worse rapidly. Over the counter hydrocortizone cream and benadryl did nothing for me. I had to get prescriptions for fluocinonide ointment (there is a cream also), hydroxyzine tabs, and clobetosol soln. The fluocinonide oint. would eventually clear up an area (anfter a couple of weeks) but then the rash just moved next door. The hydroxyzine is what really did the trick but it has to be a high enough dose. My starting dose was way too low. I am now on Hydroxyzine 25 to 50 mg. every 6 hours. I feel like a new woman. It is amazing how much the rash and itching and that extra histamine was affecting me systemically and physiologically, in many more ways than the actual rash and the itching. I also do a few other things to help:
*Keep the house cool, 66-68 degrees, especially the bedroom.
*Wear light cotton clothing with no tags and no scratchy material and it should be loose, not tight.
*Avoid any unnecessary clothing. Sounds wierd, but the clothing rubbing on the skin will get the itching and rash activated. I mostly wore a very light short cotton nightgown during the day because it did not cause itching. Pants and bras and tops and sox rubbed too much and made me itch.(I can wear clothing again now that I am on the right dose of hydroxyzine.)
*Sleep on soft cotton sheets with very light weight covers
*A fan in the bedroom helps to cool (I keep it on all night and stick my feet and legs out if they get hot)
*Use unscented and/or hypoallergenic lotion, deoderant, laundry soap, dish soap, hand soap, etc.
*Shower with cooler showers, not real hot.
*Avoid the heat (ie nice warm sunny days outside, forget it, lol, she will start itching). Really what it boils down to is to avoid getting hot. I can tell right away if the room is getting too warm ... I start itching, even on the hydroxyzine.
*Some people do oatmeal baths or use oatmeal lotion. I think these might work if the rash is minimal but if she has a systemic rash she will probably need prescription drugs. Besides, if the itching is bad and it is aggravating and also keeping her awake, it may get to be too much to tolerate. *Personally, I would go for a precription that works, like the meds I mentioned, and of those, I think the hydroxyzine (same as atarax) is the most beneficial because it is systemic and actually blocks the histamine. However, having a steroid ointment will help locally with itching and to clear it up.
20 grams of fat is definitely a lot of fat. Here are some things that worked for me:
*Greek Gods yogurt (whole, not low fat) It has way more fat than regular yogurt
*2 ounces of cheddar or Havarti cheese
*cream cheese or soft Brie cheese (check label for amount)
*liver pate - sounds awful, but I got it at the whole foods store and it was healthy and it has a lot of fat in it
*Bratwurst (I think one or two, not sure of the number)
*Peanut butter (2 Tablespoons I think) A sliced apple with some peanut butter on each slice is tasty
*Toast with lots of butter on it (this is not enough fat but it can help with other foods to make up 20 grams of fat)
*Sandwich with butter and mayonaise on it (has to be enough for 20 grams)
*Heavy whipping cream (this I added to all sorts of things to increase the amount of fat, and if I thought I was short, I ate a few tablespoons of fat the whipping cream
*Ice cream (whole, not low fat)
*Eggnog
*Nuts
*1 medium avavocado
She needs to eat some solid food with the more liquid food so she gets a little bulk in her stomach. So 2 ounces of cheddar cheese and some toast, a Greek yogurt smoothie and some toast, a smoothie and an egg or two etc.
I used to eat chicken soup and saltimes and then add something with 20 grams of fat like berries with a lot of heavy whipping cream on them. You have to get a little creative because food is not going to taste the same as it does normally. Sometimes nothing was appealing. Another thing I did was add some condiments to the plate to make food taste like something besides cardboard. I would have meat and add a bunch of greek olives or herbed olives or pickled beets or plain pickles as a side to help get the meat down. It worked.
Here is a thread with many food suggestions. Scroll down towards the bottom to a very long post by mecheng and you will see tons of foods with high fat content:

There is not a lot she can do about the malaise and fatigue although I found they lessened considerably once I had the nausea and the rash under control. I think adjusting one's expectations does help. Try to do something productive each day. It does not have to be cleaning the whole house, but maybe just doing the dishes or sweeping one room, or cleaning the toilet, etc. (I live alone so I had to do that stuff or it would not get done.) A short walk outside would be good. Take it slow. Rest as needed in between activities. Do not plan all sorts of activities in advance. Forget events for the evening ... that is recliner time. Try to get some sleep (which is difficult on the every 8 hour fat feed and pill taking). Try to adjust to not getting major projects done. Just accept that the stamina and the concentration and the motivation is just not there during treatment. I used to get frustrated because I was getting nothing constructive done. I could not work on my projects. I could not focus or concentrate. I could not read a book. I finally accepted that this is my lost year in terms of doing big projects and now I don't get frustrated or upset. I just go with the flow. However, it is helpful to find some constructive things that she can do: get audio books from the library, get DVDs (I have some educational DVDs that I watch), sort some things like photos or drawers, etc.
She will most likely feel much better after she is off Incivek.
I think the most important thing is to get those side effects under control It will mean the difference between a miserable treatment and a doable treatment.
I hope she can get things under control so she can continue treatment. I hope she feels better soon.
