I think if you look at it as a lifestyle change, it's much easier. As mentioned by onetiger, I eat out a lot less, and what I do for entertainment is much different. I think it would have been much more of a challenge if I insisted on eating out each weekend, and going to the cinema more like I did in the States. I've supplemented this with walking, going to the pub for a coke with friends, entertaining people at our house, things like that. I've even had to find new favourite treats, which has taken me about two years if I'm honest. You can find ways to cut costs, but it can be hard to know what to adapt. It is quite expensive in Britain, and we live in York, not London. Just give yourself plenty of time to find a routine, I've found that to be the best way to keep costs lower.
