Same jaw and clenching issues here, also used to love skittles but can no longer chew them. I’ve switched to hard candy or suckers. It last a while, can be very flavorful, and you’re not tempted to chew it. Jolly ranchers and the like are my new sweet go to. Also, Mexican candies infused with chili powder, so good! Mango and chili and cucumber chili suckers are SO GOOD!
