This is my first post, just like to say thanks for the comments so far - it's really reassuring to know that what you are feeling is not unique!
I had a really bad case of AF three years ago, was hospitalised for 6 days to sort it out, and have had reasonably frequent episodes of AF since then. Diagnosed with PAF, couldn't take BB, so on ACE inhibitors and calcium channel blockers. Still make me tired, but far better than BB. Have since been diagnosed with Syndrome X (microvascular angina) after a clear angiogram
Due to go into Leeds for a cryo ablation on the 8th, so fascinating (and scary!) to read about others experiences.
I'll let you know how it goes
