I worried about nausea but it didn't happen with this stuff. MiraLax and Gatorade with two tablets of bisacodyl . Last time I used golytely and it was awful. This is much better. It hasn't been bad, no nauseous feeling and no cramping. The whole is is ugh tho. Boy I would kill for a pizza right now. I've been a clear liquid s today and starving despite everything.
