I am at day 8 post op after having Gastric Bypass Surgery with Hernia Repair. I am also struggling to get what my doctor wants me to get down. She gave me a chart and every hour I am supposed to drink 4oz . That is not happening. I am lucky to get 2oz most of the time in per hour. Today was the first day that I was able to from 8a.m. to 12 p.m. get a full 9oz of the protein shake in. I can't wait to have Cottage cheese. Right now I can have broth, Creamed soup and Low fat yogurt (I like Two Good) I drink plain water and Gatorade Zero and Crystal Light. I pray this gets easier, I have had pain off and on and also severe gas at times and I do walk. Gasx has been helping with that also.
