Hi,

My boyfriend is 5 month after treatment and gets dry days and sahara days like you. His tongue then becomes brown, so he brushes it. So he gets bad days and very very bad days. He sips a lot of water when he eats and chips and a burger (which he has been craving) are out of the question for the time being.
His GP has prescribed him a saliva spray which is a short temporay relief. It's called Glandosane. It's not a miracle spray but it helps a little. He drank so much water last week because he was so dry, that he was sick water. So now he alternates when he is up and gets dry, a sip of water, a spray, a sip of water... Dig texas says the water bottle is part of his arm, Martin's bottle live in my handbag (oh and it's my fault if he forgets although now I don't forget) I am used to carrying a heavier handbag.
What also seemed to help a little with the mucus was a nebulizer. He used to nebulize 3 times a day with some saline solution and did feel a bit better after the session, unfortunately the nebulizer was on lone ans we had to give it back.
As for the swallowing Martin has a "slow triple gulp" especially with water, a mouthful of water takes three attempts to go down, but that doesn't seem to bother him too much now.
Otherwise, reading everyone else's email makes me hopeful that it might just get better.
Keep positive, it seems everyone heals at completely different speeds.
