You should look into earthing.
+1! I bought an earthing mat from Bulletproof Exec a few months back and it's had a great effect on the quality of my sleep. There are many nights during the week I can only get 5-6 hours, which is horrendous both before and after training days, but that's just my life reality. I've woken up feeling more rested ever since I started using the mat. At less than $70 after shipping it's well worth the investment, and it comes with a free, well-researched book on earthing as well.Check it out here.
