I was very sceptical about this blanket however thought what have I to loose by trying it out. For years, had great trouble sleeping through the night. First night I slept 8 hours!!! Thought, must be a coincidence. 2nd night the same!!! So far I have the odd night not sleeping through the night. I love it so much I bought a 2nd one for when I’m away. I’m feeling so much better & have lots of energy. Just love it!!! Have a go, it could change your life.
