How about doing some non-combat activity in skyrim for a while? Like Thieves Guild missions. Or maybe some fetch and delivery missions. Or Agent of Mara mission, or something similar. Or maybe do some easy missions which you know you will clear out easily anyway. You spent 3 days trying not to be OP for 2 hours?
Yes, I've been playing for days stuck with this annoying glitch. I tried to avoid combat, but I don't fast travel and I have some mods like ASIS, Radiance, Real Wildlife and Occupy Skyrim that result in increased encounters along the roads. As a result, I've gone up a few levels very quickly without wanting to. I played for hours and waited around but when I keep checking the Active Effects, it still says 2 hours left.
I believe it's related to my timescale. I play at a slower timescale than vanilla, and it took quite a while to get all the settings for Dynamic Injuries, Frostfall and Imp's More Complex Needs to have all the rates perfectly adjusted for my timescale.
Finally, after several days playing with the glitch and standing around campfires, it dropped from "2 hours left" to "1 hour left," and I noticed that it was actually dissipating, very slowly. Then I figured out that if I fast travel to the other end of the map, it would go down from, say "50 minutes left" to "45 minutes left."
So in the future if anyone is stuck with this problem, the solution is to fast travel many times. By fast traveling back and forth across the map about 8 times, I was able to make the glitch effect go away.

(Incidentally, the http://www.uesp.net/wiki/Skyrim:Out_of_Balance using the showracemenu console command, but that did not fix the problem in my case.)
