Hello everyone- I have a hard time figuring out how to post or maybe it's just the lack of food that I am becoming confused

In any case today is my first day of only liquids which means only 13 days left until surgery. When I thought I first posted this morning it was 10:30 and things were fine but now it is 1:00 pm and I am hungry. I am only allowed 3 Slim Fast a day so this morning I became a little creative and put some of my French Vanilla Slim Fast in my coffee..yummy instant creamer. Yippee solved the problem of having to drink only black coffee. Now how do I stop the headache and the hunger? Tylenol & ? I am allowed crystal light which I have been sipping on and sugar free jello...which I must still get....Well tomorrow will only be 13 days then 12 then 11 and so on. I can do it....right???
Thanks to all
