I did at first too. What I did to remind myself was, think of "W" and "V" at the same time so that whenever I thought of "Vi" I thought of "Wi" and of course to spell it properly it would be "We" so whenever I saw the word "vi" I thought of "We" and so it was automatically translated! I hope that wasn't too hard to understand.
