Yes, Sam and Guss
I have been told by a dentist that I clench my teeth at night.
I now use a CPAP machine which puffs a little stream of air down my mouth at night to prevent sleep apnea. I also take a little bit of sleep med (5 mg. zolpidem) which helps me sleep through the dreams and the hissing and farting of the CPAP machine.
I think I have had terrible dreams habitually since childhood. They are easing up now. As a tiny boy I used to wet the bed nightly. This started after abuse at age 4. My mother always told me that she had a little "talk" with me about it and that I stopped after that. Her little talks were about as persuasive as those of late President Lyndon B. Johnson *.
So I still wake up at night to "pee". Now I take an additional 5mg of zolpidem (not very much) and go back to sleep the rest of the night. It works for me.
