Replaced ~5 y/o 225 silicone mod profile unders with 350 HP gummy bear unders and love them so far!

I am scheduled for a replacement BA next wk, Aug 4th. My original BA was done almost 4 1/2 yrs ago with great aesthetic results, just smaller than I wanted. That's the troubling part for me. I have been toying with the idea of going larger, but wasn't really planning on it seriously til about 4 yrs from now. Then I got an email from a very reputable ps saying that they were screening for pts who might qualify for a BA study with a very well known, well respected breast implant company. Ultimately, one would get a $2400 discount. I went in for the consult, not thinking I would qualify, being that I already had implants, but lo and behold, I did. Yes, it's sooner than I thought, but I felt like it was an opportunity not to be missed, so I scheduled the sx. I am excited, as I have known that the nxt pair I would get would def b bigger. But now I am playing devil's advocate in thinking that I may be messing with something already good. All the what ifs of the possible complications are now rising up and making me fearful. The decision would be so much easier if I didn't love the way my current boobs look and feel, just wishing they were larger!! For reference, I am 5'2", 90lbs. I have Mentor Silicone 225 mod profiles in now, scheduled to get HP Sientra 350CC textured. Currently wear full 32B to small 32c . Hoping I'll be full D afterwards. Oh, doesn't help that when I posted my questions to docs on this site about whether or not it's worth the risk, just for a bigger size, majority have said not to, that my breasts look good now, and to leave alone unless I'm terribly dissatisfied. They were not aware of my intentions to go larger in a few yrs anyway, nor were they informed of the study discount. Here is my reasoning to go through with it:
1) I figured to go for it since they would need to be swapped out in the future anyways
2) I'm only getting older, so the younger, the better my body should withstand the surgery
3) The study incentive of 2400 discounted price essentially
4) Have an excellent surgeon
5) Better, more advanced product (gummy bear vs silicone)
Reasons not:
1) Love the look and feel of my breasts now
2) Scared to death of developing capsular contraction, or any other complication
3) Hate/dread the fact that I can't workout for 1-2 months. I am an avid yogi and cardiofunker, addicted actually.
Thanks for listening, I'm just confused at this point and my sx date is 4 days away!!! Each time I call the ps office to get reassurance, I start to feel good again, but then I get a comment from this site's PS's who advise not to do it. Ughh. I am still likely going to go through with the surgery, about 95% sure, but knw that I always have an out ultimately, even if I lose my deposit. Any advice, thoughts?

I had my implant replacement sx the night of Aug 4th. Unfortunately, my sx was originally scheduled for 4pm, but I did not get taken back til around 7:30. They were running behind schedule. However, the staff did their best to make me comfortable. Apparently, that night, I had difficulty waking up from the anesthesia. I was extremely groggy, husband said he had to force me to get out of the recovery room into the car. I vaguely remember that. Per his report, I said some choice words to him and the nurses for making me get up. All I remember is the extreme pain I had in my chest. I felt like I wanted to tear them out! Once home, he again had a time trying to coax me to move from the car seat and inside my house. (my poor sweet hubby!). What finally did it was the fact that I had to throw up, so I bolted to the bathroom. At least he got me to go inside right? First night was rough, lots of moaning in pain. The next morning, I felt 100% better after eventually falling asleep. I had my follow up appt and my ps said everything looked great. I felt they looked great too. Pain was minimal, esp compared to the night before. Only complaint was swelling and soreness along rib cage areas on both sides. Noticed some bruising there too. Ps said that was normal, and that the swelling would subside. One other odd thing was I could not see anything clearly close up. My near vision was completely blurry, and my pupils were dilated. I did some research on the meds I was taking for the surgery, and discovered that scopolamine patches could cause this as a side effect. I emailed my ps and mentioned the blurred vision. He and his nurse both called me to check in and confirmed that the drug was the most likely culprit of my visual changes, and not to worry. I was able to drive the very next morning after my surgery, and have been running small errands, like to the grocery store and window shopping. Today, I have minimal pain, some periodic sharp twinges, but nothing unbearable. I am only taking extra strength tylenol prn. I do notice this morning that my armpits and and lateral pec ms areas are very sore, like a pulled muscle sore. May be from over doing it with activities (carrying in grocery bags). The girls feel pretty hard still, but I have to remember that they are only 3 days old. Overall, I am very glad I decided to go through with it. I would def had regretted not taking this opportunity to do so. Also, I am so thankful that I came across Dr. Kortesis. I could not have asked for a better ps and staff!!! So pleased!!!

I am feeling almost 85%. They look to have dropped, but my (R) gal is still a bit higher, and seems slightly more medial compared to her sis. : ) I have not taken any pain meds since day 2 post op. Night time is the most uncomfortable, as I wake up from some nipple pain (throbbing), or pulling in my pecs from sleeping with my arms overhead (yikes, they just end up that way). But everything is bearable thus far. I can feel them soften more and more each day. I have almost full range of arms overhead and out to side, but it does pull and feel uncomfortable at the end ranges. My (l) girl is still very tender and a little fuller, esp along the inferior lateral aspect. I am back to most all ADL's, cooking, light cleaning, shopping, light stretches and sit ups w/o arms. I am pleased thus far and can't wait for even more healing to occur. : )
