I had the procedure and I wish I’d been informed that it was 25-33% effective beforehand, it would have saved me some recuperation.
Although, there was that one time I almost choked on my uvula, so maybe it was at least partially effective. My wife seems to think it was.
She had more energy and eventually lost over 50 pounds.
Before the procedure, I didn't get any sleep as I was worried about her not waking up. One time she began to turn blue.
