Has anyone experienced this? I am taking Alertec for my fatigue and I think that maybe it is from that. My mouth is so dry, I have no salava, I have been getting cankers(sp), my lips are so darn chapped from licking them. Has anyone else had this? If so what have you done for it? I can't stop the meds...I tried and I almost fell asleep at work today! Thanks for your help!
