I absolutely, with a passion, HATE the 'song' insomnia. If you can't get no sleep, then you haven't got insomnia have you?! Arghhh!
Insomnia is when you can't sleep. If you can't get 'no' sleep (as in you are unable to not sleep) then you probably have the exact opposite to insomnia. I have a thing against double negatives as a rule.
