Too much coffee can trigger headache. However, coffee can help relieve the symptoms if you drink it in the very early stage of headache. Caffeine constrict blood vessels. It helps counter the painful effect when blood vessels dilate in the head.
When added to pain medication (ibuprofen), it can help improve their absorption and increases their pain killing effect..I suffer from migraine quite often especially during my monthly period (menstrual migraine) and I have tried it several times already. Oftentimes, it has saved my day from my excruciating, agonizing headache! Try it yourself.
