I don't go to bed just because the clock says it's time to, I only go when I'm nodding off on the sofa, that could be 12,1,2,3 doesn't matter, if I forced myself to go to bed any earlier I'm like you, i'd wake up middle of the night bored looking at the ceiling, I might nod off again temporarily but only for short periods of time and when it is eventually time to get up I feel like shit and wished I hadn't the stupid idea of going to bed early to get a good nights sleep
