Got My Surgery Date! June Bandster!

I met with the surgeon, nutritionist and had my psychological evaluation all in the same day...yesterday! My surgery is set for June 25 first thing in the morning. I am glad they made the most of my trip which is 3 hours away one way. I feel a bit overwhelmed about the food situation after surgery right now. Wondering if I can curb my bad habit of guzzling water and eating too fast. Questioning if I can even get 64 oz of liquid in me by sipping all day...it seems impossible at this point. I am happy about the surgery but I am a little scared about the drastic changes regarding my consumption of food..like eating protein kind of scares me at this point. Any words of advice or encouragement would be greatly appreciated! Thanks for reading.
