How bad did I fuck up?

Getting over flu and been on Dayquil for a few days. Went out last night for fancy dinner and had about 4 glasses of Sangria. Ended up puking at 4am. I drink maybe once a month and also try not to take medicine (flu was especially bad and long)so didn’t dawn on me about the dayquil/alcohol combo. Is there chance of any permanent damage there? Or I just messed up and be more careful?
