4 day post op

I've been wanting this surgery since I was in high school. I knew my parents would say no and I couldn't afford it. Plus I thought it was a phase I would grow out of and I knew I should wait till I had kids. Well the time has come! I have two girls ages 3 and 2 yrs old. My breast never got big when I was pregnant. I was a 34b and after breast feeding my daughters I barely fill up an "a" cup bra. I'm 33 yrs old and weigh 127 and 5'6. I was debating between 350-375 cc's. I want to be a full C. However, reading a lot of the post on this site I'm now thinking about 400 cc's. Seems like there's quite a few women that say they wished they went bigger. My pre-op is Nov 5th and I can't wait! I keep wondering how much pain I will be in and when can I start working out afterwards. What are some good creams for scars so I can buy it in advance? Also, should I buy special pillows bc we don't have a recliner? Thanks in advance and I will keep everyone posted.
