Dryness my deal is still a problem!!! There is notng one can do though a vaporizer may help a bit - I've heard of olive oil and there is biotene as well you can get it at walmart. I skipped the codeine through my treatment as the day they gave me my peg spthey let me give myself a dose through my tube before I went home and I threw it up immediately. So I did without pain meds pretty much through my entire treatment. Keep a lukewarm glass of water neat your bed that may help with the night dryness - if you wake up take a sip and go back to sleep. Good luck on getting though it ... Soon you'll be at the end! Glad you figured out the rash!
