Hello, I have been on Citalopram now for 5 days and apart from a slight headache don't seem to have any physical side effects. I have always slept soundly, for 7-8 hours nightly, even when anxious and depressed, but this week I have been lucky to get 3 hours a night. I am tired and quickly settle on going to bed but wake up in the early hours and that's it for the night. I don't know whether it is the medication or, more likely, my high anxiety level at the moment as my wife has not returned home yet following her decision to leave and let me sort myself out. Trouble is my body needs more than 3 hours sleep a night and being very tired in the day just adds to things. Thanks for any advice recommendations.
