Hi, I am having Gastric Sleeve surgery in 7 days. I am 7 days into my Pre-Op diet. I am still having bowel movements that are producing solid.. It's lessening but I'm curious: 1. Is this normal? 2. Where is it coming from? My consumption is 5 Shakes per day + 64 oz Hydration Fluids including 32 oz Water, 12 oz Gatorade Zero . 8 oz Jello, 4 oz decaf coffee, 4 oz broth. I am also taking Metamicil 3x/day. Thanks you and God Bless.

Thanks to all!
