Next time, get in some acclimatization. I think your "gungy" feeling was AMS. Stay two nights at Whitney Portal, or better, Horseshoe Meadows before the next hike. That will help greatly.
And your water intake and output was pretty excessive. All those stops surely slowed your progress. I'd cut the drinking in half.
That "gungy feeling" could also could have been very early symptoms of an electrolyte imbalance. If you are peeing every 15-20 minutes you are drinking way too much water and are at risk for developing hyponatremia.
