Over the past 4 months, I have tried zoloft, lexapro, celexa, buspar, and now Zoloft again. I was given the 25mg tabs and told to take half (12.5) due to my body is apparently very sensitive to these type of meds. I was taking it at night, but i could not fall asleep. I would be dog tired, but couldnt flip the switch. I tried melatonin and benadryl but it doesnt seem to matter, its like I now have a fear of trying to sleep, my chest pains flare up and it feels like my body locks up in a panic when i close my eyes. So i didnt take it last night, actually slept a little bit better. And took the zoloft in the morning instead. BUT, i have been groggy, and plain sleepy and out of it all day. Could this be the zoloft making me tired in the morning? But yet keeping me from sleeping? Has anyone else experienced the fear of sleeping on zoloft, if so what did you do? Mr Dr told me to stop caffiene, but i dont anymore anyways. Need help with this, its already getting very upsetting. Thanks!
