You might like to research Ivabradine. It is available in the UK. I had a cardiologist suggest propranolol or ivabradine for my POTS which followed my ME and is probably viral in origin. I had a horrible reaction to propranolol as it lowers blood pressure. I couldn't stay awake and felt awful.
So eventually I asked for the ivabradine. It was immediately life changing. I take half a 5mg tablet. This costs the NHS around ten pounds. I have to pay for prescriptions so it costs the NHS very little. It is usually prescribed at higher doses for angina etc so a GP may initially take fright at the apparent cost.however this tiny dose is all that is needed to make a difference.
It seems to slow the heart just enough to allow the ventricles to fill more effectively and so more oxygen goes to the brain and body. In addition the slight reduction in heart rate takes me slightly below my aerobic threshold for more of the day. That means I am more comfortable upright and over the last couple of years on ivabradine I am slowly increasing my fitness, muscle tone and that in itself helps blood return to the heart.
Before ivabradine I used a tablet of butchers broom, horse chestnut and vine leaf from Amazon.it was helpful but the ivabradine works so much better. Drinking a bolus of water, to increase blood volume,especially in the morning, and increasing salt intake etc are all important still. I am not cured sadly, but have a Much better quality of life. Good luck.
