Actually, maybe I'm not being fair on the guy. He possibly hasn;t seen many probs with scar tissue so he probably is being honest with you. Sorry, that wasn't nice of me to say that! lol The scar tissue can, as I have experienced, cause probs with your sleeve. I certainly didn;t abuse mine. If you need a stretch, that isn't caused by abusing your sleeve, that shows there is a problem. Abusing your sleeve would cause it to stretch and allow you to eat more than is possible.
