I know that this is going to sound strange but, it was a, kind of, comfort to hear that I am not alone. I have been a migraine sufferer since I was about ten years old. I have had many test and been on many scripts for this...thing. If I do not smoke, I can/will have headaches that sometimes last up to five (5) days. They cause extreme sensitifity to light and smells. They also cause me to have nausea and sometimes vomiting. With that, loss of appetite. Weed has been my relief since I was 17 years old. NOTHING gives me the results in curbing pain, bringing back the ability to function like bud.
