Losing English

I feel that I'm really losing my English, after more than three years in Japan. There used to be days that I didn't/couldn't use Japanese at all when I was in Pennsylvania and in Montreal, but now I read and write e-mails in Japanese, watch Japanese TV programs (too often than I really should), read Japanese web pages and blogs, ...all those emersion in Japanese language has slowly overwritten my English skills with Japanese.

Probably I should read and write English more frequently, or not communicate with/in Japanese at all, just like when I was in a master's program in PennState.
