My son 29 years old has been a heavy drinker for the last 10 years. He quit drinking about 6 to 8 weeks ago. Now for about 3 weeks he's been wakin up with horable headaches. Its when he first wakes up, he says it eases off threw out the day and they r in the front of his head, not the sides and not the back rite up front. What can be causing these headaches.
