Well Im getting twitchy.. I am not even slightly tired

If I snack on a xanax too early ill buzz right through any possible sleepy moments. I know that sounds odd. When I do days of no sleep my body usually wont give up the fight until 2-3 am
My husband lays down, wiggles for a minute to get comfy and asleep in a couple minutes ! it must be some kinda dark magical business? When im not sleeping for days he says " well just lay down and stop thinking " HAHAHHA hes such a funny guy
