iv started citalopram 4 weeks ago started on 10g for 2 weeks and now on 20mg for past 2 weeks. im still not my self and iv changed from night to morning taking them as i couldn't sleeep but now feeling so tired in the day cant cope. also side affects the sexual side effects i literally cant feel anything while having sex im just numb down stairs. can anyone who had this problem did it improve eventually? at all? its really annoying me that im trying to get better and now have another issue. also does it take longer than 4 weeks to see big diffrence in mood?
