Just wonder how swiy would take this combo, Swim has a good opiate tolerance and used to be on much stronger ones but trying to stick to codeine for the moment, i havent got a tolerance realy to the prometh and valium I usually take 450mgs of codeine in one dose and I was wondering how to would be the best way to use this combo I.e Diaz and prometh prior to or after codeine, what dosages, empty stomach, immodium, grapefruit juice and other potentiation methods... Any advice and personal experiences would be greatly appreciated! Thanks
