I will be on week 6 tomorrow and really have had no side effects other than an off and on headache which isn't as bothersome as it was in the beginning. And a little fatigue, but that could just be because the dogs and I love a good afternoon nap. This is my 5th time treating and by far the easiest. Don't worry about being sick...as can-do-man and Faithdove recommended, drink lots of water and I suspect you'll get through the 12 weeks just fine. Oh and BTW, for the first time ever I am UNDETECTABLE ~ it's a wonderful feeling, Good luck to y'all!!!
My husband just started this treatment yesterday. He is genotype 1a too. So far he said he had a headache, I have been keeping his water glass full, he had a habit if not hydrating. Best wishes to you, we are all in it together.
Besides having plenty of water to drink and maybe some Tylenol on hand I wouldn't go out and spend much on things you more then likely will not need. I would guess before the sides set in your treatment will mostly be over being its just 12 weeks... Good luck to you.
