Fishslayer, I've had kidney stones about 4 times in my life. Believe me, a 7.5 Percoset doesn't put a scratch on that pain! Whatever they shot into me the last time in the ER, after they saw the stone in me, worked like all get out! Still, it wasn't something they are just gonna give me a script for! They fixed me and sent me home 2 days later. Point is, about this entire post, if you need help with your pain, the doctors know how much and when to stop prescribing. Just like I need a clean background check to get a new gun &/or my CC card, my MRIs show the screwed up discs in my back. I hope you never have any more kidney stones, too! I mean that to everybody, too! If pain meds make one sick or bad reaction, tell the doctor. They have all kinds of stuff that help for some people that don't give bad reactions. Good health to all...
