I'm on celexa now and started about 6 months ago. The first two months were pretty tiring. I was just tired all the time. But other than that i've had no other side effects.
It's worked really good for my depression. I can't say that it's help my migraines at all though.
I make sure I take it two hours before I go to bed. Just to make sure i sleep off all the cobwebs and have a better start to my day.
I've been on Prozac and Zoloft and a couple other (i can't remember). with celexa i've had the least side effects. But it has made me more sleepy that the others.
