suggestions for gaining weight please?

I'm a 33 year old man weighing at about 155-160 for the last year and dropping faster than I would ever want. I would really like to put some healthy weight on...or any weight at all would be appreciated at this point. I'm a leukemia survivor now of 15 years but unfortunately my new battle is now depression and anxiety... I have no appetite and have to force feed myself just so I don't lose anymore weight. My doc is putting my on Wellbutrin to fight this but I'm afraid of the most common side effect of losing weight. Does anyone have any advice or suggestions? Has anyone been on this med and possibly experienced weight gain? Of maybe someone just has some good tips for someone in my situation to eat better and to gain the weight? I guess at this point it would just be nice to read anything from anyone who understands to some degree and that I could talk to. Thank you much...

Hi!
Yes, wellbutrin can cause both weight gain and weight loss. What is important is to find out whether your weight loss is due to the drug or because you are not eating enough. To find this out, please maintain a week long food log. Each day log in each and everything you eat and drink—the item, quantity, time etc. It is quite possible that you are not eating enough. If that is the case, you will need to maintain another food log wherein you will write what you are expected to eat each day for a week, the item, its quantity and time. Then you need to tick each item that you have eaten. A dietician can help you with this or a friend. After following this for a month, you may see a rise in weight. Also, please discuss with your doctor about the possibility of an eating disorder associated with depression. Hope this helps. Take care!
