Where can I buy Alcohol in Qatar?

Hello, we are off to Qatar! Quite exciting, quite nerve-wracking. I will have lots of questions, and here is the first: where can we buy alchohol in Qatar? I assume can can drink alcohol at home, but perhaps not in restaurants - what is the law, and what is acceptable in practice? I can't imagine two years in the despert without a drink! Also, our stuff is on the way out to Doha - and I packed a couple of crates of wine in amongst our other stuff, is this going to be ok, or will I get arrested on arrival!? Seriously, I am now a little worried about this. Please help.
