I am 57 and have suffered from frequent and sometimes severe headaches for years. Often so bad that I would have to leave work and go home which costs $$$$. Aspirin, Tylenol and any over the counter pain killers were often useless. I cant tell you how many times I have had to plan my activities around headaches. My chiropractor suggested that my headaches may be caused by my intake of dairy products. I have always enjoyed a glass of milk with Oreos, milk with breakfast cereal, or a peanut butter sandwich, or just milk by itself. I was drinking close to a gallon a week. So I went cold turkey on the milk and in a week I could tell a difference. I was no longer waking up with headaches or getting them during the day. I am now drinking milk once in a while but in very small amounts. Only about four ounces a day (enough for a bowl of cereal or a couple of cookies). Sometimes none. What a difference. If I do get a headache it will be very minor and will go away with just an Aspirin. I hope this may help some of you.
