dried my lips really bad, it raises triglyceride levels, those are the bad cholesterol molecules. average is 200 it shot mine over 800, which is close to killing you.
i never had any luck getting rid of them till i went to the doctor. she gave me some medicine called acutane that is so strong i had to have monthly blood tests to make sure it wasnt gonna kill me.
i dont know if somebody has said this, but there is someting called no-bite that you can put on your nails and it tasts really bad, and if you bite your nails you get the flavor in your mouth.
