                        About thirteen years ago I would get leg cramps during sleep.  Subsequently, I found out that this was due to breathing thru the mouth and, thus hyperventilating.  Overbreathing caused other problems -- sleep apnea, snoring, dry mouth, hiccups, stuffy nose and many other problems, including high blood presure.  I trained myself to hold the tip of the tongue against the upper teeth as I fell asleep. After a few days the tongue would remain in that position thrugh the night. In this position the tongue acts as a valve and reduces the flow of air when breathing the mouth.  By reducing over breathing, I have esentially eliminated sleep apnea and snoring. Leg cramps, hiccups, stuffy nose have all disappeared. I still have the problem of high blood pressure, perhaps in time this, too, will be reduced.  You are welcome to contact me for further information.      David
