Oh, you have my sympathy! When I had my post-op dental pain (including dry-socket...boy, is that ever painful!....and why does it last so long? ...weeks!) the very early mornings were the worst! I don't know if it is because during the day you can distract yourself from the pain? In bed all you can do is lie there and focus on the agony. Plus of course you are not just 'in pain', you are 'exhausted and in pain'.
