I've had 2 C sections and 1 full tummy tuck. Big babies resulted in an apron of loose skin hanging over Csection scar and drooping out the leg holes of my bathing suit

and a 4 inch separation in my abdominal muscles.
To be honest, I thought the Csections were a little harder recovery than the tummy tuck. The C section cuts through multiple layers of your body that all need to heal. The tummy tuck cuts your skin layer only and suturing of abdominal muscles back together if needed. Plus, there were lots of other factors in the Csection recovery (new baby, no sleep, hormones, etc) that probably made it seem worse

The incision didn't really hurt at all, and the abdominal muscles felt like I had been through the worst abs of steel workout of my life- sore, but don't hurt if you don't move.
Mine was positive, but everyone has different experiences.
Here was mine:
I had my tummy tuck outpatient on a Friday. Went in around 6:30am and was home again around 1pm with an abdominal binder in place, a drain to each hip, and a prescription for Vicodin.
Spent the rest of the day in bed with the Vicodin. I did get up that evening to the table for dinner, but was not able to sit up straight. I had to lean back against the chair. It was about 3 days before I was able to stand up straight and not walk like a hunched over little old lady. I was off all pain meds by the end of the 3rd day too. Sleeping sucked for the first few days.
On Tuesday, I had follow up appointment. Drains were removed that day. This was the worst part of the whole recovery, imo. It hurt to have them taken out, but was over quick and a relief once they were out. (Stick a piece of duct tape to your groin and pull it off fast if you want a practice run

- just what it felt like) I got to see the results for the first time then and was cleared to drive and shower. I felt 'normal' for the first time on the way home from that appointment. 10 days after surgery had another follow up to remove sutures and cleared to lift 20 lbs occasionally. Wore the abdominal binder for about 6-8 weeks, off only to shower.
It is now a year and a half since I had it done. I'd do it again in a heartbeat.
Tips
*Bring a bathing suit to the presurgery consult with the purple pen. The incision goes from hip to hip, but they can curve it up or down depending on the cut of suit you generally wear so your scar will be hidden.
*If you have small kids, get some 24 hr help for the first week. I had a 15 month old at the time so I wasn't able to lift her in/out of the crib or carseat.
*Bring a camera to the surgery and ask surgeon to take a photo before they put the binder in place. You won't see the results until the first follow up appointment and looking at that picture will help when you are in those first few hunched over pain days post op when you are wondering what you got yourself into. If you are brave, take some "before" pics too.
*Don't expect a magic transformation. Yes, you will look better. But I was surprised to find that I did not lose a pants size. When it was all over, I was exactly the same weight, I don't know how that happened because I lost a few pounds of skin during the surgery. Clothes fit better, but no new wardrobe was needed (I was looking forward to the excuse to go shopping).
*Check out a tummy tuck forum. I used Make Me Heal.
