my friend gave him a bottle of delsym, swim already had 2 bottles of gellcaps. he swallowed 30 pills and the bottle of delsym which is about 540mgs. this isn't a half bad combo. for those of you who love the omplete loss od motor skills this is great. i took it all at ten pm, began to feel it at eleven. basically what the polistyrex did was make the trip last a lot longer, and gave it a heavy drunk feeling (more than normal on dxm hehe). a normal tip length for me is 4-6 hours, the delsym made it last for twelve easily. has anyone else tried this?
