Hi everyone,
I have only used Magnesium Citrate, it is a 10 ounce bottle that tastes like lemon lime soda. You have to buy 3 and do one and a 1/2 the the night before and one and a 1/2 the morning of. You drink 3 - 8 ounce glasses of water with each one. It is very inexpensive and can be found in most CVS's and Walgreen's and I'm sure at most drug stores. The taste is great and the clean out has been good. Check with your surgeon. Good luck with your surgery. Pearl
