I am during the day tired and in the night I am not able to sleep. Perhaps it is because of this evil winter as well of the adjustment of my body after I quit red wine.
Yes, wine and beer helps you sleep.
Heavy beers like Guinness beer help me get a good night sleep.
Another thing I notice is sleeping in a positions like a dumb cave-man help get me a really good nights sleep even if its just an hour nap.
If you think about it, its only in modern times that we sleep flat on our backs. For gazillions of years we slept on our front or side.
Of course, if you were in America, I would have recommended sleep apnea testing in a clinic. But since you're in socialist european union, tough. You've got to pull your own teeth out.
