Well done for getting this far. I had this and found that brushing my tounge using toothpaste and mouthwash really helps. If it is sore then It will pass in time and heal itself.
Keep strong and keep going!!
I must admit I am not finding LL difficult. I have so many reasons to lose weight that they constantly spur me on! My tongue looks horrid, have been brushing it with my toothbrush which has a tongue cleaning side. Will get the mouthwash out more often too.
