My fervent hope, phoenix, is that you look back in a couple of years and marvel at how easy it all was, and that you have peace and calm, and that you can sleep, and that you experience no more palpitations after your ablation. I have had two separated by about seven months. It has been bliss since the second. I went from a slow spiral downward to my first, or index, ablation, but I was in the local ER only six short days later. I, too, was put on Amiodarone for about eight weeks. I had a good period of grace for the next three months, but I was in the ER starting New Year's Eve, and presented there each of the next three days with AF. Three cardioversions lasted between 16 hours and 20 minutes, with the reduction going successively.
Ablation is not a cure, unfortunately, but it can put you into a remission of sorts. Even if you only get 24 months of respite, you'll agree that the ablation was entirely worth it. In the hands of a truly capable electrophysiologist, you'll get several good years, even a decade, before you must return with newly established AF. This is not an absolute; not every single case devolves into a resumption of AF, just a whole lot of them. The best EPs will take a second crack at you, and often, about 80% of the time, this buys you another long stretch of time AF-free.
Please don't fret about an ablation. In good hands, the procedure works, and you'll go on with your life. You won't need metoprolol or other channel blockers, and some EPs will even let you stop taking anti-coagulants if you settle into a prolonged period with no more AF. This is quite common with a Watchman implant to close off the atrial appendage because that's where a huge chunk of the risk of clot-formation lies. Once that is done, your risk of stroke when out of AF lies only in other co-morbities...if you have any. That includes aging, though.

Good luck!
