Thanks for sharing your circumstances. I hope you find a way to get on top of it. I simply was very unhappy when fibrillating. I couldn't shake the anxiety, the thumping in my chest, the belching...it was awful. While medication worked wonderfully for three full years, I suddenly found myself losing ground to the disorder, and the symptoms came more frequently until I had to go to the ER for a cardioversion. While I was sedated, they zapped me three times with increasing joules, but none of them converted my heart rhythm. Eventually, I was offered an ablation. Fortunately, the second ablation worked, and I have lived normally, albeit with more weight than I'd like, ever since. The time to deal mechanically, i.e., via an ablation, is sooner rather than when it truly becomes awful, and more persistent. Get an ablation while you're still in the paroxysmal phase, which your case seems to be...thankfully.
