plus you dont risk the chance of vitamin diffeciancy with the sleeve
Please, PLEASE---put this idea completely out of your mind, right NOW. You're going to need to take vitamins and get regular bloodwork with the Sleeve! No, you won't have any intestinal malabsorption component---but neither will you be eating like a 'normal' person. Some Sleevers have trouble with protein, because it may not get as broken down in th Sleeve as it does in a full-sized stomach, and therefore isn't as well absorbed in the gut. Same thing is true with some vitamins and minerals.
So---remember, "following the rules" does include taking your vitamins and minerals!
