Your circumstances sound almost exactly like my wife's, she tells everyone "best surgery EVER", she wished she'd done it sooner. It took her about six weeks to recover but the constant exhaustion, pain, endless heavy periods, were over immediately.

As far as what expect, you will need some help around the house for the first week or so, it's a big surgery and you will be weak and very sleepy. She slept a LOT the first three weeks but also made sure she moved some every day, as the weeks went by she started very gently exercising, by the six week mark she went back to work and while that made her tired at first she settled in quickly.

You will feel much better once you get through this, my honey says it gave her her life back.
