Have had braces for 12 weeks now and I had my 2nd adjustment yesterday. Things are moving along nicely and I'm feeling happy enough about the whole situation now! That wasn't the case for the first month where I really struggled with every element of the whole experience, but these days it's all pretty 'meh'
Originally the ortho predicted 18m pre op and 6m post but yesterday he agreed that the top teeth are just about in position already after 12 weeks (YAY!) and he even put in a nice tight square wire which he said was the penultimate wire he'd use for my top teeth. Unfortunately my bottom teeth are still bad, and in fact 2 of my teeth aren't even bracketed yet as they are so twisted. So although the ortho hopes it will be less than 18m before op it all depends on those pesky bottom teeth.
Here are some nice before pictures:

Can't get over the movement in my top teeth!
