Hi. I was wondering if anyone has had this to a degree that chewing is really problematic? I simply cannot chew. I have to eat soft foods and cut everything up into bites smaller than I would feed a baby. Still I get a sore jaw from trying to chew and I end up swallowing much to unchewed and big pieces. My questions is mostly how long it may stay so open before closing to a more manageable POB? Does anyone have any experience to share?
