I try to drink 64 oz of liquid a day but I don't think I'm even close. I probably get down half of what I'm suppose to. I am only going to the bathroom 4 / 5 times a day. I'm worried in going to get a kidney, bladder or uti. I get occasional pain in my lower back or ab. Any information would be appreciated.

In my experience....Going to the bathroom before wls is no different than after wls except that now I go more because I drink more Water. And it might be TMI but my bowl movement are much more pleasent because they aren't promoted by fatty foods.

I have a hard time with the water... So I fill up a pitcher of water with 32oz every morning and don't go to bed until I finish it. I take bottles to work with the other 32 oz in it... And make sure they are done before I get home. Yes that would be me you see downing 2 or 3 bottles on the way home because I have to finish them....lol
