Brain Fog and Blurry eyes

Hi Guys,

Brain Fog and weird kind of blurry eyes have been really kicking my ass lately. Especially over the past couple of months, I have really noticed it pick up quite a lot. My diet has been really good and clean over the past couple of months so I dont think it's that, but has anyone done anything to better help it? I'm about to go overseas for an extended period of time, so the last thing I want is to still be dealing with that as well. So please help!!
