I used to do exactly as you describe, Yogi. It is as though a compliment is permission to veer off track. Several years ago I shifted something in my brain and decided that nothing (even success!) was going to stop me. You can do that. Don't wait as long as I did.
Starting Weight: 197.5
Current Weight: 123
Lost 75# eating low carb (20-40 g) and then MDA primal low carb. Tried many other options but only LC helped me lose weight and improve health. Now at a good weight, I find my body can tolerate a few more carbs but rarely go over 100 g.
