I've been on 20mg of citalopram for around a year. At first it helped with my panic attacks but it has stopped working. I usually took the pill in the morning but my doctor wants me to double my dose to 40mg and start taking at night. I skipped my 20 mg dose this morning, and was going to take 40 mg tonight but I'm nervous. I was suprised he didn't recommend 30mg for a while first. I feel like I should try 30 at night for a while before the jump to 40mg. What do you guys think?
