I hope not to hurt your feelings, but you need to lose at least 70 lbs. You are worried about a heart attack, but with that much extra weight, you could also be in danger of diabetes. My son had a had hard time trying to quit smoking until I handed him $20 and told him to put up the extra $30 and try hypnotism. He has never smoked again and it was an amazing cure. Everyone is different, but you should try that route. If you lose those 70 lbs, most of your physical problems will probably go away.View Thread
