For the past month I have severe itching at night, all over my body and head, (no rash). It gets so bad that i have taken benedryl almost every night. It used to just happen only when I was in our den for more than 1/2 hour or when I ate anything with soy lethicin (commonly found in most chocolates). Also itch if I used soap products like Tide. So I stick with the same skin, hair, makeup and cloths washing products. I have recently started taking Solostar Lantus(15u) at night. I have known allergies to dust mites, cinnamon and soy lecithin. I have changed from a feather to a foam pillow. I itch whether I sleep in my own bed or on the sofa.
