one on one with the surgeon

anxiety level going up, tomorrow is the pre-registration at the hospital, final pre-op and the one on one with the surgeon.  the fear of the unknown is out there, what kind of diet will they tell me to start, everyone asks me how much weight I have to loose before surgery?  I haven't been told anything about it.   we went to GNC and Vitiman store to see what was available protein, iron and B12 wise will be able to purchase after meeting with the surgeon,  again unknown stuff. tomorrow I will fast and go get preop blood work and chest xray one before going to  fountain valley to the hosp.
