Hi, I m living my life as usual, sitting in class, at work, or in front of my TV/Computer at home when, all of a sudden, my vision blurs and I begin seeing black pixels that start at a small focal point and rapidly expand over almost all my vision. My head starts feeling heavier and heavier, and at a point I feel like I could just fall off of my chair anytime soon. This happened scarcely in the past before, but it s becoming a bit too frequent for my likings nowadays. I d like to point out that it isn t a problem due to lack of eating. Hope to hear from you soon.
