sorry, this is a bit off-topic but i just wanted to say that i'm in qld, and last time i tried to buy 5-htp everywhere told me that i couldn't buy it over the counter. i ended up just buying it on the internet.
Miss_C: Try Mrs Flannery's at Annerley (across from the Mater Hospital) on Annerley Road. It's a bit more expensive, but if you need it quicker than 4-6 weeks, then that's the place
