Every day I go to school my lip and throat gets dry, especially before lunch.Also when I play basketball indoors and out, my lips always get dry and white gooey stuff starts to form all over it,and it is extremely embarrassing. Even when I put blistex or carmex on it still happens.Also I have ADHD and I take things like adderal and vyvance for it, so can my medicine have something to do with my dry lip, mouth, and throat???Please help!!!
