Well, this may seem silly, but I always try to err on the side of caution. I have a questions about Tryptophan that only applies to Canada, so anyone who has bought it in Canada, please enlighten me.

Can I buy Tryptophan over the counter in drugstores here? (i.e., Walmart, Shoppers, etc.) Or do I need a prescription?

I have this huge fear of going in and asking for a drug that is prescription level and getting in trouble for it. It's probably baseless, but when I was in Britain I asked for some sleep aid and I got a lot of odd looks because it was apparently illegal to buy. >.>
