Pretty sure a good strong hot toddy (lemon juice, whiskey, water in equal portions, and a little sugar) works better and is better for you. Better = less bad.
Last time I had a colonoscopy one of my buddies drove me. We went to a buffet after everything was done. Apparently I was eating a chicken leg at the buffet while still filling my plate. Might not have had all the cobwebs fully cleared, or maybe I was just hungrier than normal. Best of luck to all concerned.
