I am new to the site, but need help. Have been on citalopram for depression just over 2 years and has always worked well. I had a dip and my sleeping has been badly affected so my doctor prescribed tamazepan which gave me horrendous side effects so im off them on docs advice. I have recently been doing a lot of research and am wondering if my insomnia is caused by the antidepressant? I am about to start counselling but feel i want to come off to see if it affects my sleep, because i have tried everything and am desparate to sleep!
