Nothing about eye fatigue, but I forgot to have any potassium for a month (err, oops, I ate lots of veggies but no leafy greens!) and my BP shot up to something

Nothing about eye fatigue, but I forgot to have any potassium for a month (err, oops, I ate lots of veggies but no leafy greens!) and my BP shot up to something like 170/90. My doctor was concerned and also confused. On the way out of her office I remembered I hadn't had any potassium for awhile, stopped by the grocery store, picked up some spinach, and a handful later (about a few minutes) the constant headache I'd had for a week straight went away. So yeah, get your potassium in.
