First time drunk... no hangover?

I drink beer maybe twice a week, and that's only started recently in the last two months. I decided to buy Jaegermiester, rum, and vodka last night. I took 6 shots of Jaeger, 2 shots of rum, and 1 shot of vodka in about a 30 minute span. I had a BAC of about 0.0113. I was so drunk I could barely stand. After about 30 minutes of hilarious drunkenness, I started getting nauseated, so I started eating. Nevertheless, I threw up about 5 times, and my nausea subsided. I quickly downed some water, Gatorade, and fell asleep. I woke up about 4 hours later and I was completely sober, no hangover, and actually felt better than before I got drunk. What gives? Why no hangover?
