I started in August of 2004, had a bit of a breakdown after doing the 14 hour a day 6 day a week work thing.... My body and mind just decided to stop... a friend of mine convinced me to go to a class - and i've never looked back! 4 years definately isn't as long as some people I know - but i'm totally committed. Congratulations on getting through your BB grading!! Would love to hear what yours are like. Ours run for 2 days and are completely full on!
