There's zero chance we'll end up with the Euro. The beauty of independence is that we can decide all those things. There would be a lengthy transitional period obviously. Initially things like the NHS would be shared.
It is and was never going to be easy but, honestly, I'll be fucking embarrassed if we pussy out because we're worried about teething issues. Norway had a very tough transition when they broke away from Sweden but it's fair to say they've done pretty well. It's going to be hard but nothing that's worth doing is easy. Just because it's going to be tough doesn't mean we shouldn't do it.
