So I am on day 4 of fluoxetine 20mg. My first time ever taking anxiety Meds. So far the first 2 days I was fine, then the 3rd day I had bad anxiety and heart palps all day, didnt sleep the night before. Now today the 4th day I pretty much feel fine again. I do smoke and I've noticed everytime I smoke I get heart palpitations bad. So I'm trying to quit bc I can't take it. And it also seems my heart is more sensitive like its been pounding a lot more lately. Do you think that has to do w the medicine? And I'm on day 4 and haven't had too bad side effects.. Do you think I can still get them?
