I know some people who have had this procedure. Those who have had it- it changed their life for the better.
If you have some self control it can be life changing. You may not see the same dramatic results as in the bypass, but it is less permanent.
It changes your life and can enhance your future- less medical problems due to being overweight, more energy.
Please: Do not ask advice on the CR. This is a serious medical decision that you need to take up with your doctor and family.
