migraine
"Been taking it about once per month for about five years. Some months none, some months 2 or 3 pills. Pill probably works 3/4 times. It seems better than using tons of tylenol or ibuprofen which gave no relief and left me nauseous. 
Better treatment would likely be to alleviate a stressors and maybe even avoid sugar, or a cocktail of stress, sugar and fatigue all at once."
