I was gone all weekend. Got home at about 1030 on Sunday night after diving until about 4:30 and having a 5 hour drive home. I got to bed late, of course. I got up at 745 on Monday morning (I "start" at 8). By 11am I was so bleary. I asked the boss if he would mind if I took my lunch early and longer, as I badly needed a nap. He had absolutely no issues with that. Said I'm salary and I know what needs to be done. All that's required is I let him know, which I had done.
Wow! I slept for about 90 minutes and felt SO much better. I ended up working two hours later that day. It just worked out so well. I'm continually amazed at the new job/boss!
