Fish oil is often use as an adjunct to anti-depressants. I have a close family member who was told to take 3000 mg a day to help them get through until their lamictal kicked in (it takes quite a while to get it up to a therapeutic dose). It does work for many people, it is inexpensive, and has lots of other good health benefits. It is definitely worth a try.

Just keep in mind that if this doesn't help, there is nothing wrong with trying a different anti-depressant. There are quite a few on the market now that don't have the side effects. The main thing is to take care of yourself.
