EVERYTIME I have one alcoholic beverage I become nauseous, I

Patient: EVERYTIME I have one alcoholic beverage I become nauseous, I make myself get sick, and then I’m fine to drink for however long/much I want. I don’t drink often but even in my younger days this was the case. After getting sick once though I’m perfectly fine. I’m just wondering if this is an actual health issue or just my body.
