i'm one of those that had a 3-fer. I had breast lift, arm lift and tummy tuck all in one knock out.
i too tried to decide if i should space them out. since my surgeon said he could do them all under 6 hours (his max under time), he left it up to me. i initially decided just to do just the arms and boobs but then at the very last second decided to add the tummy tuck as well. i'm glad i did cuz my recovery was a bee-yatch...though all of my own doing...but i digress...and i'm glad i don't have to go through that again.
in all, am super pleased with his work. my arm are nice and slim (i live in sleeveless shirts), my boobs are like teenager boobs (i can go bra-less no prob), and my stomach is (almost as) flat a board (i have 20 year olds in my yoga class who compliment on my abs on a regular basis...btw im 52).
if you have the means and the desire to get plastics, go for it. its a total game changer. the hardest part is the recovery, but if you take it slow and do as your doc says, you'll be up and at em (and looking hawt) in no time.
good luck! ❤️
