I know this quite well, because I grew up with a mother language quite different from my current language (both are not English), so learning other languages (preferably really different from your mother tongue) is always a mind opener.
I made this experience: while slowly growing into my 2nd language/culture, I extended my horizon, without loosing what I learned so far. So, it's not that I'm now inside my 2nd language, and lost my 1st experience/capabilities, but: my horizon is widened, I'm more logic and more flexible in both languages, and in my whole thinking process.
BTW, I never explicitly think in the words of my human language, words may accompany the thinking process, but thinking is so complex and fast, that you would not be able to follow directly; it mostly 'happens'...
