I did an irish stout extract kit in Dec, and noticed the same thing at about 4 weeks in the bottle. It was all hops, obnoxiously.
3 weeks later, the hop flavor was almost non-existent. Just let it age a little longer and see what it tastes like. When I emailed my LHBS I was told "I TOLD you not to drink it yet!" and they were right. It changed alot in flavor week to week until it was all consumed. I wish I had just left it alone longer so I could see what it was SUPPOSED to taste like.
