Hi @burnhambob,
I wanted to take a moment to welcome you to the Forum. 
I’m very sorry to hear, however, that you’ve been biting your tongue recently. It certainly can be very painful, and the soreness can last a little while, so I understand how this would be upsetting.
I was hoping some of our members would have stopped by to share their experiences with you, since I know there are some who have experienced this - whether it’s biting their cheeks or tongue, awake or asleep. You can have a read of some of our Forum threads on biting, as they may help both comfort you knowing you’re not alone but also provide you with some suggestions.
Our helpline is also there for you on 0808 800 0303. Our advisers may be able to make some recommendations that would help reduce the biting, as well as just listen if you feel that you need to talk about the topic more.
Please do continue to post and read through those of others, and know that we are here for you should you need anything.
Best wishes,
Joy
