If so, why?

I took my evening meds maybe one hour earlier than usual last night (6 pm instead of 7 pm), and instead of falling asleep at my usual 11 or 11:30 pm, I was so tired that I fell asleep at about 8 pm. I was dead tired! Then I woke up at 12 midnight with my heart racing and sweating. Then I fell asleep again and woke up at 3 am fully awake and hungry/thirsty.

I can't get to sleep again, but got at least 6 hours sleep. I am making Easter dinner. I made the dessert and one of the side dishes yesterday. I guess I'll have about one hour of active prep for the dinner. The rest inactive cooking. I'll ask hubby to deal with the dishes. At least the house is otherwise neat and clean.
