Clense your system the night before suyrgery. Drink fleet or laxative of your choice to ensure you are on empty. Oh and buy some gasx for post op. You will need it. Take your pain meds as often as you need them. Dont wait until you are sore before you take it beacuse it take a while to kick in. Dont have an adgenda. Just relax as long as you can. Best of luck. It was not bad for me at all.
