I've had the same exact thing. For the past 3 nights, no less. I currently am NOT on a sleep aid. My ex recommended Benadryl, which I took to humor her. ("That's what they give mental people in the psych ward". Thanks. Always gotta get the dig in).

I was slightly high, groggy and: thoroughly awake. Just like the psych ward. Finally fell asleep watching some stupid cable movie.
