B12 deficiency: I assume that you are taking vit B12 because you are deficient. Tingling in fact can be due to low B12. But vitamin B12 is very poorly absorbed when taken by mouth. The best way to take it is by injection. You can get a prescription for shots from your doctor and give yourself an shot every month or even more often - as often as every week. Tingling can also be from rapid breathing due to anxiety.
