mild OD, you'll be fine. The liver is a remarkable organ and does heal itself.
Go easy on the vitamins, supplements, and high sugar and fats for the next few days. Sugar - corn syrup - is very hard on the liver to process.
I did something similar 4 years ago - threw back 32 shots in one night (yes, everyone counted) back when i felt invincible. It was 4 days recovering.
