I'm 3 days post-op. I had a hard time drinking 28 oz of my isopure yesterday, mainly due to nausea & indigestion. Started my h2 pump inhibitor yesterday & indigestion is not as bad now. Today has been better, I've been able to drink almost 40oz of isopure, had beef broth, hot herbal tea & sipping on ice water. My friend had her surgery almost a year ago & she was like it gets better. I know I just gotta make it thru the next 4 days & I can add in the whole liquids.
