What you say makes a lot of sense. We talk about "afib" and we all experience it in different ways. My first attack was in March 15 and 7 hours and a diltiazem drip cured it. 2nd was 3 years later, 3rd a year later, 2019. Then 3 together once a week when I was adding Claritin for allergies. Those 3 all stopped by themselves at home after a night's sleep. (Nothing since then and I definitely will not take any more Claritin, even though it was cleared by pharmacist.) So I assume that Dofetilide (Tikosyn) is still helping. It sounds like I have a relatively mild form of afib. Good luck to you!
