Forgot that this is the all knowing board! I would get these migraines that felt like something was pushing my eyes out from behind them! In 96 or 97 I started wearing a Citizen Eco-Drive dive watch (still wearing it) and have never had one since. The timing is/was a definite coloration! Other than being a coincidence based on some other change in my life, I've always wondered if it was the stainless steel against my skin 24/7, as I only remove it showering, or the electric impulse from the watch? I'm prepping for the wise guy answers!
