Based on your comment I went to read others by chessplayer. He's been here for five years. In a recent posting he called Obama an "empty suit". He strikes me as more of a curmudgondly iconoclast than a HuffPost troll.
I also saw this, which may explain his absence. I have myself sometimes posted things on the way out the door and not been able to respond until several hours later.
I'm giving him the benefit of the doubt.
I have what are called ;silent; migraines. (migraines without the pain) Often I get spots/flashing lights in my eyes. Sometimes it gets bad enough that I have to sit down because of the disorientation. I had my eyes checked because I thought I was getting glaucoma and that was causing it, but the tests showed no sign of glaucoma. The doc said the silent migraines (spots/flashing lights are being caused by changes in the tiny blood vessels behind my eyes. Dilating/constricting. I take afternoon naps, and the episodes occur in the the hour after I get up
I’ll do the same.
