Getting super tipsy from one can of beer. Is this normal?

Yeah i know how this sounds and no I’m not an alcoholic. I had a beer the other day and got really tipsy from one can. This has never happened to me before. Usually I’ll have a couple beers and feel absolutely fine, and when I’m at a party I’ll have up to 3 shots’ worth of vodka, and 2 of those are usually in the form of a mixed drink, and only thrn would i feel a little tipsy. But for some reason this can of beer completely whacked me out. Does the brand matter? Maybe it’s the weather? Someone help me out here. Thx.
