I hope it works for you...try a banana before bed, sounds weird but I was doing some reading on getting a good nights sleep and that was one of the suggestions.Yep, that involves getting up. I just did it in an effort to wear myself out so I can sleep again tonight.

I struggle with not sleeping well from time to time, more often lately. Not fun at all.
