Is it possible to have 1 drink, not even feel a buzz, then throw up randomly 6 hours later?

Yes or no?

It was a very weird experience! I had 1 drink and a sandwich around 7:30. Drove home at 11:30, went to bed then woke up and threw up around 1:30. Totally random and I'm not sick! Has this ever happened to anyone?
