Haha good ol mouth breather dry mouth.  You know what the worst was?  When I had my braces taken off in grade 7 they gave me a retainer to wear at night.  That thing dried my fucking mouth out sooo bad and got uber uncomfortable, needless to say, it didn't get worn very often 

  I actually don't have too much of a problem with it without the retainer, but when it's extremely dry or something it may be worse.  Water by the bed is always a good idea.  I keep a water bottle becaue I always end up knocking over the glass of water when reaching for the phone or to throw the alarm clock hehe.
