To me the benzo headaches are only comparable to the headaches I had when I was on BCP for a short while. During the 7 days when I was taking the placebo pills, good Lord, I wanted to throw myself through a window headfirst and land on my head and split it like a coconut. Same thing with benzos.
You are right though, we are so much closer to healing. Luckily for me, Ibuprofen helps, but just rest as much as you can. Try not to overdo it when you feel good, and stay hydrated. Oh, and watch your blood sugar as well. Try to avoid foods that cause severe spikes.
