The GP increased my Citalopram dosage a week ago from 20mg to 30mg. Each day since I have been feeling more and more down. Is this normal? I am nearly at the stage where I just couldn't be bothered to do anything. I am forcing myself to go out, keep busy etc to try and life my mood, but nothing is helping at the moment. I know my mood is worse this time of year so I bought a sun lamp. But that doesn't seem to be working anymore. Last resort ECT I think!
