Instant nausea from anything stronger than wine

My body just seems to absolutely hate when I drink anything stronger than the average wine. It’s not that I dislike the taste of stronger alcohol, or that i have drank too much. It’s just the moment i drink it, i become so nauseous that i have to stop talking completely and sometimes even lay down for about 5-10 minutes. It’s hell. The thing that bothers me the most is that i know i used to be able to. When i was younger i used to chug cognac, vodka etc. like a moron, now i can barely touch it with my tongue without feeling sick.

I just wanted to ask if anyone else reacts this way, if anyone has any idea why, or if anyone just has a tip that can help.

Thank you:)
