I had a few consistent themes in mind when I finally started down the path of getting "sleeved":
1) I had pretty much given up dieting because no matter how successful I was with the diet, I always failed and gained all of the weight back. I entered my 30s at approximately 240 lbs in the best shape of my life after losing about 100 lbs. By 31 I was back at 270 and by 33 I was right at 300 lbs. For me, I no longer looked at a traditional diet or behaviour modification as holding any real promise of being successful...
2) My father passed away a few years ago and I really started to think about my own mortality. I have heard that you "never see" 300 lb guys in a nursing home and I realized that the onset of various co-morbid conditions were clearly showing me where I was headed. Moderate sleep apnea, bad cholesterol, borderline high blood pressue, family history of diabetes and heart disease are serious and I realized I didn't want to be the guy that ignored the writing on the wall.
3) As part of early weight control, I developed a love for excercising (i.e. sports, weights cardio etc.) even at heavy weights 300+ lbs. At 40 I realized my body was starting to fall apart under the strain of the excess weight. I am hoping to avoid hip/knee replacement and the things that will definately occur if I continue to try and be active while "heavy".
I have wrestled with thought of getting the sleeve for about 18 months and really think it will make the difference that I need to be successful long term!
