I also have the headache from hell!
My coworker, "Princess" (our BFP hat model), is also wanting to get in better shape and has been complaining of a headache for the last couple of days. We figuredf out that cutting out sodas, tea, and most of our refined sugar was the culprit after reminiscing about our weekly runs to Chili's to share a red velvet molten lava cake.
Those once a week runs were costing us $5 a piece and almost 500 calories. EACH. Even though we were sharing!
