If you're interested in playing around with supplements, I'd really recommend mugwort tea. Its not very expensive either. If you're in a fairly big city, all you have to do is find your nearest New Age-y shop, maybe a head shop will have it. Might have to order it online, but it should still be very cheap for a whole lot of it.

When you make it, make sure to actually let it boil for a little while. Boiling it wont hurt the active ingredient (thujone) at all. Or, if you prefer, you can roll it up and smoke it. It has a really herbal taste when smoked. As a tea, it just tastes kinda grassy. Not good, not bad.

Edit: And dont drink it too often. Maybe a couple times a week. Thujone is fairly harmless, but consistent long term use can cause a toxic build up.
