I would like to point out, reading my post above, that I DID take 3 drugs at once. That is probably why I did the serious damage. (And I was already fucked up from overdoses on combo drugs I had as a teenager, before ever finding out about RC's) This update is being posted years later, so hopefully it will help someone. The twitches come and go. I haven't had them as bad recently. But I don't do 4-FA anymore either.
