My tongue and gums don't burn. I never really paid much attention to my saliva and I don't really have much of it so I'm not sure. Maybe in between I guess. Other than my eyes I haven't had any complexion problems except the Acne which is gone now except for scarring because of yaz. I do have really pale skin I don't know if that means anything. As for my weight I don't put weight on easily, more like the opposite. I was only 110 lbs at 5'6 when all this started to get really bad, now I'm down to 104 lbs because I've skipped a lot of meals due to the fact I'm at college alone and rarely have the energy to get out of bed to get food anymore. No one in my family has had any health problems like this. My parents have way more energy than I do and neither had any real Acne problems, discoloration under their eyes or insomnia or any of the things I've been dealing with.
