I got 3 capsules filled with pure DXM this weekend. I watched my friend take 3 of them on Friday and he tripped pretty hard, but the problem is he is very very big (like 5'10 250 LBs). Based on research I've done, the effects you get from DXM are directly associated with how big you are. My other friend who is about my size (5'7 135 LBs) took 2 and had a horrible trip, he took them by himself in his room and he was throwing up all night and couldn't stop itching and his whole body was burning up. Since I'm not sure on how many Mgs are in each capsule it is hard for me to figure out how many I should take. Any advise?
