Airmom,
I am not sure what your situation is, but in my case I simply used my parents address as my US home address for my US drivers license, credit cards, bank statements, etc. My folks then put together a package and send me my mail every month or so. I've tried to go paperless wherever possible and this has helped reduce the mail.
I tried switching some of my US accounts to my UK address a few years back and it just seemed to cause more problems than it fixed, especially since I still have a big chunk of credit card debt in the US. Once all of my US debts are clear, I will probably close most of my accounts and switch the remaining ones to my UK address.
