Dear Candice: You want to drink tea or coffee, but it causes headaches. Caffeine is a vasoconstrictor and this is probably why. However, you can reduce your headaches by taking two supplements and within a day or so the headaches should be better.
Often for me taking 1,000 mg/day of sodium ascorbate and some magnesium for a couple of days will often help. If that is not enough, then taking some vitamin B complex since this is often used to help certain brain functions also. Magnesium helps smooth muscle relax, vitamin C reduces the body's sensitivity by providing the antioxidants the body needs and vitamin B will normalize some problem glucose metabolism and these should reduce the headaches in a matter of days.
