I bumped this up because Twila brought up heart issues.

Yahoo Autonomic Neuropathy. It occurs when the nerves start malfunctioning on the Autonomic level. I have been hospitalized 7 times this year because of it. It helps to know what it is and try imagery to control and calm symptoms when they start veering up. However, that doesn't always work, and then I have to get to an ER for sedation to help get my functions back to normal.
