I've just moved up from 30mg to 40mg of citalopram 2 days ago. I've gone from sleeping a lot to getting 3 hours a night and I feel hyper a lot of the time. I have so much energy, I'm jittery with it. Just wondered if anyone else has experienced similar and how long it lasted? I mean it's lovely to no longer feel suicidal but this is the other end of the scale and feels alien!
