24 Years Old, No Children, Large Hips, No Breasts

I've wanted breast augmentation done since I was 16, but never seriously looked into it. However, I'm turning 25 this year and have recently lost some weight. I was lacking in the breast department before, but now I barely fit into a B cup bra. My large hips make my breasts look even smaller. I've been feeling very self conscious and never go anywhere without wearing a VERY padded bra. I'm just so tired of feeling like a little boy, so I bit the bullet and went for a consultation.
My consultation was such a wonderful experience. I discussed the procedure in detail and tried on different sizes of breasts. I was so happy I booked in for the procedure two months earlier than I expected to and will be having surgery on September 1st. I am slightly nervous about the need for heavy pain killers as I hate being high, but am otherwise ecstatic.

3 weeks until my surgery and I get more excited every day. I spend hours obsessing over the reviews on this site for BAs, and continuously wish the time would go by faster. My only concern right now is how/what to tell my coworkers. My office manager knows because I told her when I booked the time off, but she's the only one so far. The only person I know I can't tell is the dentist that I work for. He is very awkward and I know he would rather have me not tell him. I'm just not sure if I should not say anything and only tell those who notice, or if I should just tell everyone and be out with it. I'm open to suggestions if anyone has advice :)

Four days until my surgery and I'm starting to get very excited. I'm still a little concerned about having to take heavy pain killers, but I'm sure I'll be fine. I've posted a few more before pictures to show how wide and disproportionate my hips are.
