I have about half a cup around 7 am, and another half a cup around 10 am. I have cut my coffee consumtion a lot. I never drink soda, or eat chocolate, tea with caffiene or energy drinks. I cut my coffee back over the year, thinking it would make a big difference. But celiac and lupus both cause headaches, so I don't know what else to do. I drink tons of water and coconut water, I am hydrated well.
