Hey Caley,
I basically had the same thing done, a little more extensive work on the forehead and chin, but it won't be as bad as you think probably. The experience will most likely be similar. Mine was three weeks ago tmrw with Dr. O, as you can see from my avatar, the brusing and jaundice are gone. I still have dark circles under and above my eyes, my forehead is still raised, I am still swollen in the chin and jaw area. I can tell you that the first 5-7 days after surgery, while painful and very real while I was living it, feel like about 3 years ago now. They will pump you full of some good drugs so don't worry about the pain. It hurts at the time, but you probably won't remember it.
The drawbacks...I am having frequent headaches, I'm tired all the time and I can't get electrolysis for 3 months. I was ready to go full time after ffs but I'm going to let my face settle down a little bit first. Give yourself time to recoup, I have a hard time doing that
