Thanks for the information .... everyone.
I've opted for the Slim Fast Optima. I saw the Glucerna, however I wasn't constrained to it since I don't have Diabetes. The Optima had fewer calories and it was about 2/3 the cost of Glucerna. The taste is good but I'm only had one Rich Chocolate so far. Since I'm less than a week away I'm going to be drinking quite a few of them.
I have no doubt in Dr. Ortiz, or I wouldn't let him poke holes and put foreign objects in me later next week.
Once again, thanks for the info.
