Vitamin toxicity is a condition in which a person develops symptoms as side effects from taking massive doses of vitamins. Vitamins vary in the amounts that are required to cause toxicity and in the specific symptoms that result.
B-12 is one of the water soluble vitamins -- meaning it should not build up to toxic levels in your body like fat soluble vitamins (e.g., Vitamin A) can. Your body should just excrete the excess through urination. Since you stopped taking the supplements several days ago and your symptoms persist, I doubt they are related to the B-12 supplement.
