What is good for sleeved pre-op and post-op? Need something I can get on the go.

smoothie King's can be dangerous - they slip a lot of sugar in stuff if you don't tell them not to, and their calorie counter doesn't do a great job dealing with different sizes and certain customizations.

That said, I do drink them sometimes when that's all I'm planning to have for the first half of the day. I'm about 9 months out, and I usually go for the small chocolate gladiator with strawberries (or medium if I'm super hungry). Half of it goes down for Breakfast and half for lunch.

They have a few reasonable choices in there, but I was surprised to find a lot of them didn't have enough Protein in there to be worth the calories .
