Hi, I'm also day 2 of my pre-op diet. It's not been too hard so far, but I had the advantage of having an upset stomach the first day, so no hunger pains-lol. Unfortunately for me, I am this close to surgery and still do not have insurance approval. My surgeon and his bariatric team kinda did things backwards . Hopefully all goes well and I do not have to start over with the pre-op diet. But, on the bright side, weight lost is weight lost !
