I've done a lot of dxm man. that shit is wicked but it can also kill you so if i was you i'de pass. I started with cough syrup and then to coricdin which is probibly why im so fucked up (Lol im not really). Anyway, my point is just dont do coricdin. If you gunna do it, buy some robo with just dxm in it. have fun and make sure no one that can get you in trouble is around cuz they'll know your trippin on something.
