hi there im new to anti depressants as well, my first type(prozac) didnt help but the 2nd(remeron) tpye has been a lot better in helping some of my symptoms............
I had no appetite and lost weight and i also couldnt sleep, the 1st type didnt help at all, it reduced my apetite further. so when i finally got myself back to doctors(after 2 weeks of not taking the pills and having a bad time withmyself) and told him what i had expierenced and he change my anti d
and now things are starting to improve - the side effect of my new anti d is sleepiness and the munchies -
what im trying to say, you dont know what side effects you will get, but as like in my case the side effects maybe good for you.
the prozac may be the anti d for you, it maybe the next one, its hard to let your doc know everything what your going through but try and him/her knowhow you think the anti d is affecting you so they have a better idea of how to treat your syptoms of depression.
Best wishes and hope things start to improve for you
