I would go to bed but my old dog gets a pain pill in about an hour - and I would rather stay up than wake up to give it to him. And I don't want him in any pain. I would give it to him now, but that would mean waking up early to give it to him in the morning. Anything that has to do with me waking up and giving the dog a pill is a bad plan. The last time I tried that, I was so sleep dopey (and I did not have a head cold to blame) that I spilled all the pills and had to keep the other dog from eating them.
