Have you checked if your insurance covers Celexa? Celexa & Lexapro are very similar.
I have tried a few different ones that effected me with a lot of side affects. I just started Remeron, with hunger being my only side effect (just for an hour after I take it, it subsides the following day). I take it at night right before I sleep as it was perscribed to me to help my sleep, anxiety & depression. You should definately do some research on prozac before taking it. I wish you well.
