It's 2:00 in the morning, I have a dentist apt at 8:00?

Every time I lie down my tooth is killing me. He replaced the filling 2 weeks ago. My husband is frustrated with me because I won’t stay in bed, but it only hurts when I lie down. I have been taking Motrin for 2 weeks. Any midnight cures? (My husband would be even madder at me if I got drunk, so don’t suggest that) HELP!!!!!
Oh man, now it’s starting to throb sitting up! Augg!!!!!!!!!!!!!!!!!!!!
