Natural depression remedies?

[away_she_flew]

I've struggled with depression for years, and am finally, happily, on a drug I like. However, I'd like to go off the meds and handle things on my own (I would most definitely work with my doctor, of course, when I do this). Plus, I can't take the meds I'm on when I'm pregnant, which is in the near future for me. I'd like to get everything under control before getting pregnant, too.
So, any tips for natural depression help? I know about the SAD lamps and I can't afford one right now...maybe in the winter.
Thank you!
