I like the clear mix the best as it doesn't have any flavor. I mix it in 16 oz. of water so that it isn't so thick, and then follow it with a glass of juice. It is quite helpful for IBS, my doctor recommended it. It's not harsh, although you do experience some gas and bloating at first while your body adjusts to it. I started out taking it once a day for about a week and then increased to twice a day. There's a lot worse stuff that's out there to take. This really isn't too bad.
