question: Can the dietary supplement Lean EFX cause mouth sores? I have been taking it for ten days. It causes dry mouth so I am constantly drinking water. About three or four days ago I got a sore on my gums and swollen taste buds on the tip and side of my tongue. Today the entire tip of my tongue began to hurt and have a numb feeling. Very painful and hard to eat anything. I expect this will all go away in a couple days but I am wondering if it is from the Lean EFX. Any ideas???
