Since a year, I sleep with a machine which send me air all night long, I use this machine because I suffer of sleep apnea. Due to my job, I use to work on day or night, that 's not help. I was tired the day with some small sleep was needed, and during the night I was sleeping good for a few hours then wake at any time.
Since I use this machine, and I heard that more and more people use it, I sleep much much better, and since the morning till i go to bed, i have more energy, I work better and don't need small break during the day, when I have to drive for long distance no problem anymore to fight against fatigue.
I still sleep bad when I drink to much, specially white wine, or strong alcohol, first hours sleep good, but then eyes wide open with high heartbeat. I drink also less as before, but still feel sometimes like young
Also with this machine I don't snore anymore (if nt drunk).
So all benefits for me, and for my wife too, she's more happy now.
