I was able to drink just fine but now I can’t

So long story short I used to be able to drink fine and get drunk happily but then I got really shitfaced like throwing up for a couple hours kinda shit faced and now I can’t drink anymore without gagging, so how do I recover from this, my incident was on Saint Patrick’s day and I haven’t been able to drink since. I know it sounds like a good thing but I wanna drink and have a good time with friends and family you know, so what’s a good way to recover from this.
