bro, if you are going the hard core route and that is shooting them, you don't need anything else with them. The high is so great you will NOt want any other drug to even fuck with it.. as for snorting or swallowing, that just made me feel like i had eaten a hydrocodone. But as for feeling bad bro, when i shot them it was like there was no distinguishment between days, it may be friday and it felt like wednesday, its not a great thing, i'd stay away from this drug if i were you, if you like opiates, grab a handful of vics.
