3 Guinnesses and 3 Strongbows isn't a lot of alcohol!? Dude, that would knock out a Killen!
I like BevMo too. Try picking up a 4-pack of Beamish next time you're there if you haven't tried it before. It's a super yummy Irish stout that is something like Guinness, but with something of a coffee taste! Frankly, it is delightful!
