Pre op diet and constipation

Did anyone experience severe constipation with their preop liquid diet? If so what did you do to help? I do not want to do anything that can irritate my stomach prior to surgery.

 Are you drinking enough other fluids, besides the shakes? If you're having trouble, try Miralax and/or the Clear and Natural Metamucil. 

I wasn't constipated at all, even though I was taking iron supplements. I actually had watery diarrhea the first few days, then it was soft. I probably drank between 8-10 cups of water or other clear liquids per day. 

I did benefiber in my shakes so I stayed fine.  Start something now and you can continue it after surgery if needed (very likely).  I found miralax to be better when I was more stuck but these days, daily benefiber works fine.

Thanks!! I really havent been drinking water.
