Well the biggest issue with getting it out of your system i think , is that its fat soluble , not water soluble, so the bodies usual and fastest processes dont act on it . Unlike most other psycho actives, which are processed much faster . A couple of days even. But thats jsut the mode of action as far as i understand it . Not a solution , so useless i suppose.Ive been toldit leeches out of your fat slowly, but i think that may be urban legend.
Its only speculation ,but i agree with endlessness, just keep your metabolism up and healthy, drink coffe, excercise a lot.
There are also websites that sell Tea's that claim to do all sorts of things. look into that.
