I'm not sure why but I've felt irritable after the gym I'm not sure if its because I drank a pre workout and it's just not getting out of my system I kinda have a paranoid feeling and a weird feeling in the back of my head. I just keep telling myself it's just side effects from going from 20mg of celexa to 10 and I've only been on 10mg for a week or 2 now. Any opinions?
