Some morning I am forced to wake up at 4:30- 5:00 in the morning because I have such an excessive amount of saliva I can't sleep. I can not continuously swallow it because not only will I be swallowing every second, I will also feel the build-up of saliva in my stomach. I often spend the next 5 hours spitting continuosly, into a cup until ieventually, the amount of saliva flow sarts to slow down.

This occurs on completely random days (sometimes a week or 2 between occurrences, sometimes month between occurrences, and this time it hasn't happened in about 10 months)

Do any of you know how I can overcome this?

Perhaps there's a medication I can take on the morning I have this to stop the flow of excessive saliva?
