Welcome womanway!
Sorry for the reason you're here but glad you found us.
It sounds like you're herxing and I ask what are you doing for detoxing.... If you're not familiar with these topics, please take a peek at these links..
On herxing:
www.tiredoflyme.com/the-herxheimer-reaction.htmlOn detoxing (and why it's essential):
www.tiredoflyme.com/detox-methods.htmlWith you having A-fib, I hope that one of the first herbs you're taking is Hawthorne. In fact, I'd be looking in Buhner's books for specific recommendations.
What exactly are you taking now? I'm not aware of any of the herbs Buhner recommends for Babesia coming in capsules. He recommends tinctures a lot.
No matter what, you might want to consider backing down on your dose and either increase your detoxing/slowly start a detoxing protocol that you add to continually.
Herxing delays healing. Detoxing is our only way to help move things forward.
Oh, please read through our "New to Lyme" thread that sits at the top of the forum. It has an incredible amount of useful information including detoxing tips and much, much more. I think you'll find that you refer back to it time and time again.
