I'm having an awful time with dry mouth which started when I started taking meds for copd--Spiriva, xopedem, Musinex. I've tried everything. Hot drinks, cold drinks, tools, fingers, cloths, Biotene, weeping with frustration. I tried giving up these meds (one by one) but couldn't do without them for more than a few days. I've been reading your posts now for a few weeks and find them very positive and helpful. If you have any tips for dealing with this, I would be so grateful. I'm elderly and figure something else will kill me before copd does but the dry mouth is ruining the quality of the life I have left!
