Alcohol became repulsive

The last 2-3 months i started drinking. I’m 18 years old and a male. The first couple time were fine i drank i got drunk and i was perfectly fine to do it again. Last 2 times i drank i threw up. It was like nasty to me. Today i tried to drink and i was genuinely repulsed with it in my hand. I drank some grey goose which was always my favorite and even that was gross. I genuinely feel sick the second i touch alcohol and when i put it down im perfectly fine. Did i develop some kinda intolerance? Is my body telling me to stop? I’m so confused
