I just had my surgery on 9/14. I had 2 weeks of optifast products prior, and then two days of clear liquids. By the day before surgery, I had to leave work early-couldn't think and multitask. During the optifast, most of the time (after the first two days) I was not hungry-just seriously missing texture. I have taken off 2 1/2 weeks after surgery......hoping to be on pureed foods by my return.
