This kind of stuff becomes more interesting when you take in account that not everyone functions the same.

For me, it didn't really do much other than tingle my tongue. My buddies though it was amazing. But I also have a very high opioid tolerance; I would take 40-60 mg of oxy for physical therapy briefly, when it was supposed to be 5 mg every four hours, to get my leg back into working condition, the surgeon was surprised that I regained all of my function in a month. That's after having a bunch of screws and a metal rod jammed inside of my leg for context. They gave me tramadol as well, which I stopped taking after a few days because I heard screaming and yelling (auditory hallucinations) while on the toilet. Daily Ibuprofen use will make you bleed out your yass. Daily Tylenol use will make your liver die faster than drinking everyday. I'll be in chronic pain for the rest of my life, but hey I got to keep my leg, so I'll just have myself a beer.
