I used caffeine. The question is, bluebicycle, what are the stakes? Can you afford a manic episode in your life? Are you married? Children? Do you have a career? Do people depend on your stability? If not, then although it's risky at least your stakes are pretty low. I suppose you could say that you can afford to do it.

I cannot afford to do what you're doing. I have a wife and children who need to me to be as level as possible. I have a job to support them which needs me to be stable.

I hate to be a bummer, but using stimulants to trigger mood malfunctions is not normal or healthy. It's sounds like you're becoming an addict. Meth and Coke in your future I see.
