I had an immediate LD flap reconstruction and no implant, so a bit different, as it was an all in one operation.
Cosmetically the result is fantastic, and I am very happy with my choice. I have a big, but faded, scar on my back tha runs roughly under the bra-line (depends which bra!) and a totally natural cleavage. 18m on I still have some tightness across my back if the atmosphere is cold or damp but it eases with gentle stretching. I have numb skin on my back, under my arm and on my breast.
In terms of recovery, I was told to take 6-12 weeks off work, and I took the twelve (which was all the time I had off in my treatment, I was lucky) Recovery was good but I needed help around the house (I live alone) with hoovering and heavy tasks for most of that time. I was driving after six weeks and able to get out and about after about one. I found I tired easily to start with. I'd say a minimum of six weeks off work, but allow for more.
I hope you get some input on the other options, and whatever you decide that the result is great.
