So far no one's had any weird side effects from it so I think you'll be fine trying it out.
Unfortunately that's the order it usually has to go by.
I am, but I'm over in NYC a lot. My daugther's friends live out there so we shuffle around a lot. I refuse to spend the winter though if I have the choice - spent the last ten of them in England and I'm very much looking forward to an LA one again.
