DCS - Add my name to the "Caregivers Club". There is so much compassion here as well as a wealth of information. During my son's Tx, what saved my sanity and kept me from falling off that depression cliff to which I was hanging on by my fingernails at times - was checking back here every day, several times a day. Going out (as you mentioned) even if just to the grocery store and taking some deep breaths in the fresh air really helps. When nothing seems to work for the person you are caring for, you have to keep trying because you will find something that does! And sometimes, something that quits working at one point, will work again when tried later. My son had used the "Magic Mouthwash" but after a while, it didn't work anymore. Then, later, when he went back to it, it did work! Another thing for dry mouth is "Stoppers 4 Dry Mouth" or if that is not available, the Biotene products. You are doing a great job - and things really do get better! Check back often and let us know what's happening.
