I know everyone that posted before me has more experience but I'm more of the attitude of do whatever you want to do and make your own decisions about it. This is a hobby after all.
I really like all the tips and experience I get from these boards but there are certain things you want to learn on your own and I think this is one of them. You just brewed your own beer. Want to try one? Awesome, try one.
My second batch has been bottled for a week and I tried one. And it was good. Not great but good. It certainly got me excited about what it will taste like in the future. Am I sorry I tried it because it will mean I have one less beer in the case three weeks from now? That's one of the silliest things I've heard. If that last bottle makes me wish there were more, guess what, I'll brew another batch.
If you decide to wait 3 weeks to try one now, or in ten batches from now (or never) who's to say that's not cool? But I think it's important to come to that decision yourself.
Just my inexperienced 2 cents.
