I have been taking citalopram for a month now for my anxiety. I started on 10mg the first two weeks and now I'm on 20mg. The first two days were okay but by the third day I started getting super tired and had to take a nap just to get by with the rest of the day. I also feel really unmotivated to do anything even stuff I love to do like going out with my friends like it just doesn't seem fun anymore. I also feel like my brain is foggy like I'm kinda out of it like the feeling you get when you over sleep even if I didn't sleep too much. What can I do about this?
