Late Night Focus

Many of my writing occurs late at night, in the middle of the night, after procedures, or maybe even a drink or two when I am able to have a drink. 
I've always wondered why I suddenly get a flourish of concrete thoughts that I can put in writing at these odd times. 

For one thing, at night is when most people are settling in for the night. I, personally, like to wind down, cuddle up with a blanket, read or write, have some tea, maybe do a light yoga session, and end with watching a favorite show or listening to the spa music channel. When I am all relaxed, obviously there is less going on in my mind than if I am up, busy, running errands or being all domesticated. 
The other thing is that I can finally relax and focus my thoughts more concisely when I am in less pain, and since I take my pain medication late at night, this makes sense. 

It is incredible how much energy pain sucks out of a person; how much brain space it takes up. 
I have mentioned before, when I am in a really awful flare-up, how I can't seem to keep memories during that flare. Well this is the same idea. It is almost as though when I am in less pain, my mind can finally focus on something rather than constantly being distracted by the pain in my stomach, back, shoulders, eyes, head, chest, hips... The pain in these areas are constant... Always there... So a large amount of brain activity is taken up simply by being in pain. 

At night after taking all of my proper medications to attempt to at least dull some of these pains and after procedures that include anaestheic, I can finally organize my thoughts into concise explanations, sentences, stories, or just general thoughts and opinions. 

Who knew pain could take up so much of my every say thought processes?
