Erin,
I had the same thing happen to my appetitie when I was on cellcept and Imuran. It makes it difficult to take all your meds when you don't feel like eating. It is certainly not silly to be afraid of CHF, I have often thought of that myself being on all of these medications. You are doing a lot of the best things, eliminating salt. But do see your PCP asap to find out what is going on. As far as your head getting hot, that didn't happen to me on those meds, but sometimes that happens with hormone fluctuation. You seem young for that

I hope you are doing better and keep us posted on what your PCP says. I'll be thinking of you! Dorothy
