Blood sugar crashes tend to follow spikes. Carefully analyze your diet to keep your sugar level constant. It will likely take some time to get it ironed out.
I also used to get crashes always followed by headaches. I had to eliminate as many simple sugar as possible.
I don't get super analytical myself, but low glycemic diet may help you.
