I chew my tongue, excessively, and I cant control it. This has been going on for almost 2 years now. I've been seen at several hospitals, I've switched my Primary Care Physician 4 times now, and I've done research, and I still can not find any answers to what has become a very painful annoyance in my life. I do this all day long, everyday, I stay up all night chewing it, and once I finally fall asleep, I wake up because I've hurt myself from chewing it in my sleep. I tried to change tooth paste, mouth wash, different foods and drinks, I chew gum, nothing seems to work and its damaging my teeth from the excessive chewing. People tell me that I can stop, but I honestly cant. I only chew the tip, and around the edge, and sometimes if I feel as if I have a 'swollen taste bud' on the top (close to the front) then I will chew the top as well. I feel as though I'm chewing off taste buds, and once I feel swelling, or as if the taste bud is growing back, I chew it over and over. I need answers, suggestions, anything, PLEASE!
