Shit dude, you guys are lucky. With that little you really don't have to worry about your livers and shit. There's a lot of people that take way more tylenol than that every day for a fucking headache. But to answer the question about oxy, it's the same opiate buzz. More powerful, more dangerous. But in my opinion it's a better choice if you have a high tolerence or are using a lot, because theres no acetominophen in the time release oxycontins. Be careful, I didn't believe I'd get addicted and build a tolerence, but I'll eat 8 of those 7.5s and barely get off, and that led to me using way harder opiates.
