Hi , i had a terrible dry mouth about a month before i was diagnosed (approx 4 months ago) i also had dry eyes and dry nose it seems to have calmed down a lot since i started low carbing i still have a dry mouth at night but the dry eyes have more or less cleared up i dont have to use the visco tears every night prob only once or twice a week and the nose is ok if i use a bit of vaseline but the mouth i really dont know what to do with i was thinking its because i cant breath through my nose it makes it worse , i do get up once in the night for the loo but have always done it so its not an issue for me , however these are the only symptoms i have ever had ,i dont get the bad thirst or tiredness that a lot of other poeple get, i hope someone posts with advice for the dry mouth
