best of luck to you. My brother in law had his surgery about 24 months ago and he has been able to maintain to about 20 lbs from his goal. He also is no longer dependent on a sleep apnea machine, isn't experiencing diabetic symptoms, and has taken up scuba diving (being proud to don a wet suit). His depression is much better too.
I am rooting for you as I'm sure the rest of the group is.
