Jo and Jimi are your best friends right now. They both have years of experience with big boas and can guide you when you need guidance. I think Becky might have a bog one also but I can't recall right now
Anyway, my point is this: You have a network of support and I urge you to use the network for the big girl. PM people and ask your questions. This forum is wonderful for support, encouragement, problem-solving, and, well, most things!!
Again, you're a hero in my book
