I had it done years ago and have never regretted it! Having boobies is nice ;)
The best advice I can give you is to do lots of research on your own and then see at least 3 surgeons for consults. Doing both of those things helped make my decision much easier about who to use. And look at pics if they have them.
One doc I went to-OMG-every single girl had these huge goldfish eye boobs! Awful!
Another wanted to only take me from an A to a B and do an extra procedure because my nipple are a little "poufy". Excuse me? They look just fine to me lol!
The last doc I went to talked about choosing a size that fit my body, explained he would never do anything extra to my nipples because there was nothing wrong with them (nipples come in all shapes and sizes!) and with my fair skin there would always be a visible scar around my nipple (ewww), which way he would place the implants so that I wouldn't have visible scarring, etc. I didn't feel like it was a one-size fits all doc. He was actually taking the time to come up with *my* plan of treatment.
But having learned a lot on my own really helped.
Afterwards, it wasn't too bad. Just had to take it easy for a couple of weeks, I slept on a wedge for a while, needed someone to help me get off the bed for a couple of days, that type of thing but very tolerable overall.
forgot to add-I had mine done *before* I had kids and didn't have any problems nursing either of my little ones (16 & 20 months!) The doc went in under the fold rather than the areola.
