Here are some tips for the occasional snorer:
Lose weight and improve your eating habits.
Avoid tranquilizers, sleeping pills, and antihistamines before you go to bed.
Avoid alcohol and heavy meals (or snacks) at least four hours before you sleep.
Establish regular sleeping patterns. For example, try to go to bed at the same time every night.
Sleep on your side rather than on your back.
Raise the head of your bed up four inches. Raise the whole bed, not just pillows.
