Even if you choose sedation instead of general anesthesia, you will be in a deep state of sedation such that you probably won't remember anything. I have done implants over the muscle under local with sedation, but I think to do sub muscular implants that way, it would be almost impossible to both make you comfortable and have you breathing on your own. There was a tragic death of a girl from Wisconsin a few years ago, who went to Florida for her breast augmentation, which was not done by a board certified plastic surgeon, in fact the person was not even a doctor. Make sure if you have your operation done in an office, that the plastic surgeon has privileges to do the surgery at a local hospital.
