Hi junebug.. I know angie and pj have you covered.. But I literally just got my expanders out and got my silicone implants in on the 18th..of september..I had fills every two weeks of 50 to 100 cc until I got to 650cc. two days of discomfort...walk, walk it helps.  I has 800 cc silicone implants put in ...that's the largest they make. Had the discomfort again thru the weekend.. but it's nothing compared to your first surgery.. and the expanders do alot of the work ahead of time..so I started my inflation in june ..done sept...and just fyi I took a flight in between..and I was so afraid the expanders would set something off..but they didn"t..enjoy florida.. also have a female plastic surgeon..they are a wealth of knowledge..and also have amazing empathy for your feelings..good luck, lia...get nipples etc after 3 months...(after holidays)
