dont know if u already got an answer, but im saying this so you dont get hurt.
>Drink 2oz (maybe a bit less.. see how u feel, then more) (takes about an hour to kick in depending on how long ago you ate) of it mixed with something carbonated (absorbs in stomach better) and maybe jolly rancher to add some flavor
>DO NOT MIX WITH ALCOHOL - thats how people get hurt
>i wouldnt do at party, makes u wanna sit and relax and do nothing.. not party haha
and what to expect.. its the same high as pain pills (vic,percs, ect.). relaxing, mellow, calm, happy, feel good. Youll like it, but its expensive as fuck... so dont drink it too much
EDIT: make sure it is actual CODEINE WITH PROMETHEZINE
OTC cough syrup like DXM will get you high.. but has to be done probably. the other active ingriedients will make you soooo sick if you dont know what to look for. Goodluck, pm me if u need anymore help/advice
