I am so sorry to hear that you are feeling hunger pains. I did not experience this VSG on 12/28/15. Try Switching your protein shake. It will get better and easier for us all.
just think about how happy and healthy you and your husband will be together. Three days i was on for two days. No worries hun imaging the finish line.
The pre-op diet is the hardest thing you will go through in my opinion, but you can do it. Good luck on your upcoming surgery and making it through the pre-op.
