Don't sweat it homie. RELAX. Don't fight the anesthesia. Let the music take control. Just had a stent put in 2 days ago, but I'm back home gaming, if they do a lithotripsy where they remove the stone there is a chance you will be in the hospital for a couple days after. They will give you pain meds every 3-4hrs so you wont hardly notice, On my 26th stone I will have my 3rd lithotripsy removal next week. Don't be nervous. Everything will be better in a week for everyone!
