I started my pre-op diet on Monday and I already fell of the wagon yesterday, first off my diet should consist, 2 of 3 meals will be replaced with a a protein shake then a healthy meal also a snack of sugar free pudding, popsicles or jello. I did good till dinner yesterday went to taco cabana ordered a cabana bowl with rice, lettuce, cheese and grilled chicken, I knew it was bad but I still did it... Also I am not a water drinker and I have not been drinking but a bottle a day, my surgery is scheduled for 4/11 :-(
