As a newbie here I am just coming across a few of the ongoing posts. I wanted to let you know that I feel all your pain, anxiety and frustration about not sleeping. I am another person who has a VERY hard time getting and staying asleep. The only time I have to do my training is in the evening which can make going to sleep difficult, plus I have Restless Leg Syndrome so some nights my legs keep me up even if I am dead tired.
I met a person who has neuropathy and he swore by this stuff called Resurrect, so I bought some. Knocked me out cold. It's made by a supplement company called Fahrenheit (look it up to see if it contains anything you are uncomfortable taking). Just a warning, I took a HALF a dose and woke up the next morning with a hangover-like feeling that lasted most of the day.
Now I take just a small amount (barely enough covers the bottom of a small scoop) and it is much better. I have to say that I still wake up during the night (mostly my age - I'm 48) but going back to sleep is soooo easy. Another warning - it is expensive. I bought a small tub for almost $30, but at the rate I use it, it should last a very long time. I really hope this helps others, it sure made my life a little easier. I don't use it every night, but after 1-2 nights of not sleeping, I will use just the little I mention above. Morning coffee will get rid of any residual sluggish feeling (very minor).
Best to you.
