Binge eater here in a similar boat. Am forced to laxative purge due to chronic constipation, but it wasn't always this way. Can't stand how addicted I am to the sensory experience. Not just the taste, I don't feel satisfied until uncomfortably full. My interoception is fucked and I usually don't even feel normal hunger or fullness. Just irresistible cravings for the sensory experience. It's more than useless, just totally destructive. My health is pretty bad at this point and I keep hoping it ends up being my bus ticket suddenly.
