Similar story here. I was dealing with headaches every weekend, and it turns out that not sitting at a desk and drinking coffee on the weekend was the cause. I gave up caffeine completely, and after a week and a half of headaches, the problem was gone. This has been about 4 years now. I consume some caffeine now but try to keep it under 60mg a day or so.
