How long does the effects of a blackout last?

Last weekend I got blackout drunk for the first time. I’m not usually a big drinker at all (I drink like 3-4 each weekend but no more than that) but I got severely carried away with myself and ended up on about 14 drinks over the course of 3 hours. Yikes. Anyway, as this is the first time I’ve ever binge drank, and certainly the first time I’ve ever got drunk enough to blackout, I had no idea the effects would be this bad. I’ve been a little dizzy all week, not feeling exactly “there”, if you get me. Nothing else, just mental stuff. So, my question is, how long do these effects usually last, are they normal and have you ever felt like this before?
