I'm about to have a breast augmentation. I don't want to go under general so my doctor told me we can use epidural anaesthesia

Selected patients may opt for local anesthesia with sedative rather than general anesthetic. However, only your surgeon will be able to decide if you can have the local anesthesia. Discuss with him/her your concern and his/her rationale for opting to use subdural anesthesia, which is not a routine procedure in this case.

Thank you for your inquiry.  I certainly understand and appreciate your concern about having a general anesthesia for breast augmentation.  I have been performing breast Augmentation (under the muscle) for over 40 years using local anesthesia and sedation without problem.  I encourage you to discuss this modality with your surgeon as this is easily performed and in my opinion much less complicated than having an epidural anesthetic (which would be pretty unusual for this surgery).
