I woke up and my eyes were swaying left to right uncontrollably! It's happened to me twice now?

Nobody is going to diagnose you without a proper examination, and you only get that from a doctor. We, strangers on the internet, can only guess at your condition and offer general advice. I advise you to study some books about nutrition and learn how to eat right. Magnesium might be involved. Magnesium strengthens muscles, calms nerves, stops cramps, and fights infections. Get epsom salt. It is cheap, five bux for a year's supply. Put a dose in a glass with water to cover and stir until it dissolves. Fill the glass with lemonade and drink it. You can take it without the lemonade but you won't like the taste. Milk of magnesia is more expensive but nicer tasting and gentler laxative action. Your choice.

You need to learn a few things about nutrition because doctors have no training in that field.
