I'd been putting off a sickness for a while, but also working 12+hour days for over a week. Today my body had enough. Just when I thought I was feeling a little better my head started hurting so bad I couldn't bear to have my eyes open. So I crawled into bed for what I thought would just be an hour or so... about 6 hours later I managed to crawl back out.
Proof that you can push your body for a while, but then it'll want to go into Sleep mode to run some cron jobs or something. Feeling much better now!
