Hi! Just over a year ago I was diagnosed with POTS (and later other conditions that caused this). Originally, I managed my symptoms pretty well with compression stockings, a high salt diet, and propranolol (which is a beta blocker). This stopped being effective for me after a while, so I switched to 0.1mg of Florinif once a day and 2.5mg of midodrine three times a day. Recently, with an increase and activity and warmer weather I was really symptomatic (dizziness, blacking out, etc.) so we increased the meds. I now still take the Florinif, and take 5mg of midodrine four times a day. I'm trying this for a bit and will either increase the dosage or switch to something else. About the beta blocker- I stopped mine for the reason you said- my BP was going way too low and making things worse. It helped at first with the tachycardia, but the other side effects weren't worth it. But everyone is different!! Maybe talk to your doctor about increasing the frequency of the midodrine? I went to 4x and so far it is helping! When I feel myself "flaring" with POTS symptoms I try to get extra rest, drink TONS, and exercise lightly if I can (walking, slow biking, etc.) to make sure my legs don't get too weak and to keep the blood moving. It doesn't take away the symptoms, obviously, but I feel a bit better doing so. I hope you feel better ASAP. I know how frustrating everything can be- if you have any questions or ever want to talk I'm around!
