anxiety
"Switched to Effexor XR after having severe anxiety side effects with Prozac 20mg. With Prozac initial side effects, I didn't sleep for days, constant, ceaseless agitation and restlessness, ended up in ER for psych evaluation which has never happened to me before. Doctor switched me to Effexor XR 37.5 mg and on the second day I noticed that after taking the pill in the morning, by the afternoon I was much calmer, almost drowsy, which was an enormous relief after two weeks of severe anxiety. After two weeks on Effexor XR I'm doing much better; much less anxiety and worry. The PM drowsiness has gone too. I hope to stay on the low dose."
