Hi,
Has any doctor considered that you might have
Fibromyalgia or Chronic Fatigue Syndrome?

Maybe Postural Orthostatic Tachycardia Syndrome (POTS) ?

Do you faint when you are going from a sitting position to a standing position?

Do you have other symptoms?

(I'm not saying either one of these is it, but I wanted to toss them to you in case the info is helpful.)

also
POTS from the mayo clinic regarding Beta Blockers
