The dollar is weak now anyway isn't it? That should mean you'll get more £££s for $$$s. Maybe you should've changed all your dollars into pounds before they sorted out the debt thing in Yankieland.
Miffed is right, by the way, if you reach a point where you have to rent your own place, it's fucking ludicrous in London and the general SW. It's not difficult to find places much cheaper, while being an hour or so away from the outskirts of London, places like Southampton, Birmingham and Bristol. It's not so bad if you're working in London and earning London wages, but if your income is 100% poker, you'll be earning less in London than other places. It's worth a thought if circumstances change and your expenses increase.
