The danger of taking too much Vicodin is that it has a shitload of acetaminophen (Tylenol) in it and if you take more than 4000mg of Tylenol a day for for too long, your liver will go to shit and I mean SHIT. FDA is about to change a lot of laws regarding combination meds (with Tylenol) due to massive amounts of liver failures. Percocet is the same except it has Oxycodone in it instead of Hydrocodone and that's pretty much like heroin. Take enough Oxycodone (chronic pain, years worth), there's no getting off that shit, the doctors will be increasing the doses until you're wearing patches (Fentanyl), sucking lollipops and popping pills 24/7 just to sustain the opiate addiction... the good thing is that opiate tolerance pretty much has no ceiling, the bad thing is that it gets really really expensive.
It's really scary.
