Hello, I suffer from chronic headaches and have since I was about 12. I am now 24. I have seen my doctor, a woman I like and trust several times and we have done CAT scans, blood tests, and talked about my diet. I am generally healthy, though very slightly overweight. I drink plenty of water and take supplements (including B vitamins, including B12 which I apparently do not absorb easily through food) and the last piece of advice she gave me after exhausting these avenues was to keep a headache journal and attempt to find any correlation between times of day, things I had eaten, etc. When I began seeing her I gave up all caffeine for 3 months at her request and noticed no difference. More recently I have also begun to feel tired all of the time, especially after 3, lethargic, and unmotivated. I get at least 7 hours of sleep a night and have consistently for the last year..any advice?
