I doubt that a small change in seat height would account for your problem.
I ride the hills at least every other day, sometimes consecutive days, but I do get rest. It seems like on the last few rides, I would get about 1 1/2 miles into the ride, get to the first big hill and have no steam to climb. I use a camelbak so I get plenty of water during the ride, I drink ice tea at night, and water during the day at work. I eat breakfast, carbs and protein. I usually eat chicken for lunch, and a huge salad and pasta (sometimes add a little chicken) for dinner. I really don't get what the problem is. I was doing so good and improving then it was almost back to the starting line. Just a total lack of energy.
