This is one of the reasons I won't take antidepressants. I've worked long and hard to keep weight down. And if I suddenly began to put on weight as a result of taking an AD, the weight gain would make me even more depressed than I already am. Currently I do take Clonazepam in part for my anxiety. But primarily because it is helpful with a couple of other non-mental-health issues I have. Thankfully it has not had any effect on my weight.
