Hi growling,I can definitely identify with your problem. Keep the faith! I had it past the one year mark and figured it would be a quirk I'd have to live with forever. Sometime in the second year I realized it wasn't happening any more. I can't tell you at what point. It just stopped.
I totally understand. I'd be at meetings and people across the room would offer me food, thinking I was starving!
The only thing I thought set it off was when I ate something that irritated my wrap or stomach. If I had dinner salads, or lots of raw veggies. Things that are a little rough going through the wrap.
I wish I could give you the magic key to stop it all now, but I can tell you that with time your GI tract will adjust to the changes and it will subside. You can't rush it, you just have to wait patiently.
Maybe somebody will be by who knows more about it than I do, but that was my experience. Hang in there! There's hope!
Take care,
Denise
