if the protein shakes helps with fullness? Also I dont know how many calories a day I should be comsuming at two weeks, its nowhere in the packet they gave me. I read people eat around 600 so I have been trying to stay around there but who knows!?! I drink protein shake in the morning, nectar chocolate. in the morning I do feel full but for me is at night that I get hungry. I dont drink the shakes at night though... maybe I should... Is just I am tired of the shakes.. but let try again.. hope that will this hunger. You should be on something like Prevacid for the reflux your tummy can have. My understanding of it is that even though your stomach is 75-85% smaller, for a while it still produces the same amount of acid as it did before, and that is why doctors want you on a daily PPI. If you aren't taking one, you also may feel hungry, from what I understand. You should be on something like Prevacid for the reflux your tummy can have.
