It is not really considered a diagnostic referral site, but I always suggest people check out the erowid website (
www.erowid.org). They have a lot of information on medications and do a much better job of talking about off label uses of medication than other sites. you need to take what's said with a grain of salt as much of it is self described experience, but they do have good information on almost every medication and drug out there and some of the few descriptions of street drug and prescribed drug interactions I have seen anywhere on the net ( not that I condone street drugs or suggest that any of you are using them, just saying the knowledge base is pretty big).
