After scouring every tooth, bracket and wire residing in my head, I attached the necessary elastics to their respective hooks and posts and betook myself to bed.
Two and a half hours later I woke up with my jaw screaming in pain. Only one thought on my mind, I fell out of bed and made my way in the dark to the nearest pair of scissors. When I found them I stuck their points between my teeth and began to snip. The elastics stung when they snapped but the relief in my jaw was so great I hardly noticed.
I've got to remember to take ibuprofen before bed. I don't think two and a half hours a night is enough time to correct my cross bite.
