I had my band two days ago and one thing I remembered from all the reading is drink slow, which I have and have had no problems. I also bought a magic bullet which is easy to clean and works very well. I did not have to do the pre -op diet and actually gains 9 pounds my last month of waiting. I have enrolled into a test program for the doctors so we are doing things differently. I am off my sugar pills, BP pills cut in half all the rest are gone. No sickness just some soreness like I have been doing allot of sit ups.
I have had two TKR and one revision in 9 months so this wasn't near as bad. But eat slow, drink slow and you will do just fine, walk back and forth the house or go out side. "Weight Loss Surgery", for dummies is a great book to read it covers everything. "The Real Skinny on weight lost surgery" is very good also. Good luck its not bad at all.
