I'd forget about 5-htp. Took it for a month once at 200mg, did absolutely nothing. Well for the first week after reading the effectivness of it on various forums it seemed to work very mildly, then I scanned the literature for peer reviewed studies on it and found out that it was merely comparable to placebo, and since finding that out it stopped working. Typical effect of placebos, if you think they work they will, if you don't they wont. Only thing I find it helps with a tiny bit is comedowns after doing too much MDMA.
