Soooo I have been on 20mg of citalopram for the last 6 weeks, but felt like it wasn't really doing much for me. Had a really bad headache for the first few days of taking it, but no other side effects, and the headache was bearable. Anyway, as I felt that it wasn't doing much for me, my doctor decided to put me on zispin, 30mg, and I didn't do well with that AT ALL, had really, really bad side effects. So I've now been told to take 20mg of citalopram again for about a week and then up it to 40mg, but I'm just wondering if this'll be 2 big a jump, and if I should maybe try 30mg for a while first? Also, would I experience any side effects in jumping from 20mg to 30mg, or from 20mg to 40mg, etc? Thanks!!
