Yep, I have one. I started drinking together with some university mates yesterday at noon and didn´t stop until late at night. The excessive ethanol consumption also led me to "getting involved" with my ex-girlfriend later on...shit happens but it was fun though and we both had a good laugh when we were talking on the phone about last night two hours ago. However I think I will refrain from drinking for a few days considering that I´ll have to give a research presentation on Wednesday and haven´t prepared anything so far.
Next weekend I´m gonna head out for Boston with a couple of friends so that´s when the next hangover is gonna be due considering the competitive nightlife of that city.
