Why do my lips, tongue and gums get numb when i'm drinking alcohol?

Side effects: Alcohol is a central nervous system depressant and can have a host of side effects on your body. If not metabolized fully, it can result in toxins being released and can have short term effects such as these. You may be more sensitive to this than others.

Drinking to much: Try to drink more water to see if it gets better.
