Actually I guess it's closer to 800 with the chicken, but yes the pre op is a week before and just the 2 shakes, yogurt and 4 ounce chick and steamed veggies.
I think the lack of sugar - that was my weakness sweets- has made a huge difference, around 2 pm I get a bit nutty and think about cheating lol but usually if I can get past that it's not too bad lol
I am having the gastric sleeve on October 19th! Doing pretty well on the pre-op diet, getting excited and nervous after reading through all these posts!
