Never. I have this weird thing where my liver doesn't process it correctly. If I have one beer I'll throw up for 3 days.

"When most people ingest alcohol, which contains ethanol:

An enzyme called alcohol dehydrogenase (ADH) helps metabolize (process) the ethanol.

Your liver converts the ethanol to acetaldehyde, a substance that can cause cell damage.

Another enzyme called aldehyde dehydrogenase 2 (ALDH2) helps convert acetaldehyde to acetic acid (vinegar), which is nontoxic.

In people with alcohol intolerance, a genetic mutation (change) makes ALDH2 less active or inactive. As a result, your body can’t convert acetaldehyde to acetic acid. Acetaldehyde starts to build up in your blood and tissues, causing symptoms."
