Long story short, my wife had stage 1 breast cancer a few years ago decided on a double mastectomy and was prescribed OxyContin for pain. She hates pain pills and had quite a few leftovers. I had a massive headache one day and decided to nip this thing in the bud. I took 1 and was like wtf no big deal I'll take another. A half hour later I could barely stand up and had to lay down from the cold sweats and the room spinning....no fucking thanks on the heroin.
