@danarosef I thought I was drinking a lot.idrink 400 liters of water 2 times a day,caffeine free sugar free A N W.somtimes water drys my mouth, I drink 1 full glass of water when I wake up. Then have my 1 cup of coffee. Then water n I sip on my flat soda all day long with water. Do you drink your water during the night? I can’t as I use mouth tape. Do you get painful bumps on your tongue? I’ll go 2 weeks without them. Then I’ll go a week with them. I’m trying to slow down on the flat soda. I use the biotine mouth wash, dry mouth toothpaste, dry mouth mints, sugar free hard candy, it all works for a little while till it’s gone then I get the dry mouth back. I just don’t know what else to do.thank you for replying.
