Heh I had quite a bit of that at my place and had a neighbor that would come over and say he had a headache all the time and ask for one. I gave him the rest when I moved.
Do you wake up with a headache often? Do you every dream that you are drowning or that you are being suffocated? Do you fall asleep during the day or while driving? I thought that I sleep apnea at one time. I even used a cpap machine. I found out later that the real cause of my problem was that when I turned over in my sleep. my penis would flop over my rectum and cut off my air supply. Once I learned to wear a jock strap to bed, all is well. Barry
