I have taking a generic for celexa, until recently I was satisfied with the results, but I had noticed weight gain. I called my doctor and asked to be put on something which would help with the weight gain. What a mistake, she put me on zoloft and now I have not only gained 5 lbs in the week I have taken it, but I cannot sleep, suffer from headaches, suffer from food cravings at night and taking clonazepam is not helping. Under normal circumstances taking 1/2 of a clonazepam would give me great rest. Last night I took, 1 and 3/4 and still could not sleep. Needless to say, I am going back to my other antidepressant. I am small boned and when I gain weight, My blood pressure goes up, which then requires me to take pills for that. I don't want to go on blood pressure meds just because of the weight gain. Hope this helps someone.
