Hello! I am new here and I have been an anxiety sufferer since 2002. I've been on many different SSRI's and they have eventually all done the trick. 2 years ago when I was pregnant, I was having anxiety and my doctor put me on 10mg of generic prozac. It worked great for 2 years. All of a sudden last week it didn't help anymore. Just like that. I went to my doctor and she upped my dose to 20mg. The first few days I was really shaky and nauseated, no appetite, insomnia. Now I'm on day 5 of the new 20mg dose and I feel like I'm crawling out of my skin. I have no appetite and my limbs are tingly. Am I going to get my appetite back and will all of this pass and I'll feel normal again? I am a full time working mom and I just feel so crappy. Please help me and give me some hope. I feel so helpless.
