Trying to get back on track

I had my surgery 17 months ago. I am 5' 7". I weighed 247. Had to do the two weeks of liquids prior to surgery. I was 227 the day of the surgery. By March (8 months) I was down to 175. I have had problems with heartburn and vomiting on and off. Right now I have very little in the band. (don't know how much) I have been eating way to much and foods that I shouldn't be eating. My weight yesterday morning was 184. So...yesterday I started the pre-surgery liquid diet. I plan on doing it for a week. Hoping to eliminate the sugar cravings and to get myself back on track. I would like to get down to 155 although that may be too low for me. I will have to see how I look and feel as I get closer to my goal!
