Oxycodone really doesn't have any significant long term side effects. 30 mg of oxycodone is pretty high, but not enough to kill you. The acetominophen is a problem though. 975 mg at once isn't dangerous, but it's very long lasting, so if you're taking all three doses of 975 within 12 hours it's barely any different than taking 2925 at once. More than 1500 can cause liver damage. Its especially bad if you take that high of a dose daily, because it's still active in your system for 24-36 hours, and stays in your system for days, so it's just constantly building up. If you continue this, you're bound to have liver failure at an early age, and it's very hard to get an organ transplant if the damage is caused by non-prescribed drugs. Youd have to get a transplant from a friend or family member whos giving it specifically to you. There's a really simple solution to this though. If Its prescribed at that dose, ask your doctor for a non-acetominophen brand. If Its not prescribed, just do a CWE (cold water extraction). It takes 5 minutes to do, 30 minutes to sit in the fridge, and another 5 minutes after, plus you just need a few cups and either a coffee filter or paper towels. You can find how to do it on youtube, but watch 3 different videos to make sure they're all consistant. Sorry about the length of the post, I take 3 different stims daily.
