I have no pre-op diet as well, just instructed to not gain weight. I will not learn well until I am forced though, hence my lack of self-control on my own that has gotten me to this place. So I don't feel as prepared for what's to come after surgery this way. I am scheduled in May, and am anxious and grateful. Gotta knock off the coffee at the least, as I don't want a headache I cannot take medication for post-op. I will miss my morning cup of coffee, and noodles
