Why I don't give up

Generally, I think the drug I've been taking to calm my legs and help me sleep is more trouble than it's worth. But then I have nights like last night, where I sleep soundly between about 12:15 and 7:45. Not so bad.
Granted, I did have to wake and go upstairs, but that was pretty early, around mindnight. So I'm moderately well-rested and working on a Monday.
