There a few entheogens that you can check out (there are many sources of them on the internet, just check out the For Sale thread), but I'd recommend quitting if you're becoming even somewhat dependent on it. I hate feeling weed as an obligation, so I'll sometimes take a month or so to clear my head. I'll just head back into the wrestling room, it really helps to keep my mind of things; the only down side is I end up spending just as much money on dip as weed, but it's all good.
