I snore fairly loud I suppose (how am I supposed to know...I'm asleep!), loud enough to wake my wife up nearly every night. The major problem there is that my wife and I play pranks on each other all the time. Her strategy is to wait until just a few minutes after I fall asleep to start jacking around. So, when she wakes me up for snoring too loud I usually go into a fit of yelling and telling her she plays too much, thinking she's trying to be funny.
I'm going to pick up some saline and nose strips this evening and see if that will help
Another problem that only creeps up every now and then, I throw punches in my sleep. This has resulted in what I was sure was a broken knuckle one time when I caught a metal futon frame, and me rolling into a 2 foot gap between the bed and the wall in a hotel on a seperate occasion. I've never hit anybody, but I do worry about it. On most nights I'm told I twitch or shake, but it doesn't turn violent often.
