Help for POTS?

Greetings,

Please tell me your experience with postural orthostatic tachycardia syndrome (POTS). What helped you manage or recover from symptoms? What triggered it initially for you? What caused it to flare up and worsen for you, if anything?

My body is a chemistry experiment already from treating Lyme, so I am especially interested in non-pharmaceutical remedies. Has anyone tried biofeedback? Neurological re-training programs? Breath work? Physical therapy? Diet (aside from salt)? Homeopathy? Acupuncture? Herbs? The more detail the better, please.

I have posted in other forums on healingwell.com but there don't seem to be many people familiar with POTS. Even though it affects the heart rate and blood pressure, it's technically neurological in origin, and can be secondary to other conditions for which there are forums, so I posted on those forums first....

Thanks so much. Feeling pretty desperate here.
