I got them as a 40th birthday present for myself (can you say 'midlife crisis?'). I have 3 kids breast fed them all for >1yr so the girls were not exactly perky. I actually got the smallest ones, 250cc of normal saline, which made me a 'full C'. (Had a lift as well).
The recovery was brutal and I have a great tolerance for pain. If you've ever breasted and have become engorged, that's how I felt every day for at least 3 wks. Couldn't open jars/ bottles, wiping my kitchen clean, pulling open doors at stores . . . .you can't believe how much you use your chest muscles every day till they've been cut. I stayed out of work for 10 days (I'm a nurse, pretty physical job).
My husband thought I was nutty and honestly never thought they were great/better/ etc than ever. He's just that guy who loved me when he met me at a 100 lbs. and loves me now at . . . .quite a bit more ;-) . I had trouble w/ blouses that buttoned down the front pulling and looking tight so that wasn't so great. I loved that buying a bra wasn't like the search for the Holy Grail, trying to find one that fit.
2 mos. ago, for their 8th birthday, I had them removed, and honestly feel much happier without them. Call it growing up, (at 48?!), growing old (more likely) or whatever you'd like.
Good luck w/ your surgery and recovery. Make sure your doc is a board certified plastic surgeon etc. I don't regret having them, but I don't miss them either.
