I take 40mg of celexa each morning and it works well for me but I also feel like regular exercise helps me just as much, if not more than, the anti-depressant. I highly recommend exercise to anyone suffering from depression, as some studies have shown that it can be as effective as an anti-depressant in treating depressive symptoms. I am by no means anti-medication but rather pro-exercise, plus it doesn't come with any negative side effects and is free to do!
