I was also banded on the 7th. I had a rough first three days, but yesterday I felt alot better. Enough that I overdid and had a rough night. I am just on a liquid diet with lots of protein drinks. I can only drink small amounts at a time and it takes a good hour and a half for one 10 oz glass to go down. Haven;t had any nausea unless I drink to fast. But am taking reglean every six hours for nausea. Maybe you just need more protein in your diet, I know if I don't drink mine I do feel light headed. Best of luck to you, keep in touch and let me know how you are feeling in the next couple of days.
