Hi, I took 10mg citalopram for 10 days as instructed by my doctor, then upped to 20mg. Since then, I have been awake from 4.30 in the mornings and can't get to sleep at nights. My mind is racing and I can't relax at all. Have also been getting shaking attacks in the middle of the day and headaches. I took citalopram 5 years ago and don't remember these side effects. Will they get better or should I go back to 10 mg for a while longer first, or come off them altogether? Did anyone else have this and it went away? I can't deal with the sleeplessness as I already had sleeping problems before the medication, now it is even worse.
