At 65years of age developed left knee problems. Have only been overweight since mid 50's and was sure that if I just tried harder, focused a little more, gave up that glass of wine etc. I could drop this weight. That is just not going go happen. I am an RN, eat a healthy diet, exercise and still weigh 215 ,lbs. I am waiving the white flag and will have a gastric sleeve 6/18/14. I am excited.
