I was on 20 mg of Prozac for several months and just felt "dead"...no emotions, tired all the time, etc. I stopped it and am not trying wellbutrin. So far I have tried effexor, zoloft, lexapro, and prozac. Maybe #5 will do the trick. If not, I give up. This is no life going from one med to another. I also found out I have sleep apnea so my fatigue could also be attributed to that. I am wearing a breathing mask now.
