I have had POTS for almost 11 years now, I was diagnosed when I was about 18ish. I remember thinking what the heak???? My Mom has POTS and mine is genetic my brother also has it. I take 20mgs of Adderall once a day and I have almost no symptoms. I do get dizzy around my menstrual cycle and I will have my days when I fell like poo, but I overcame the really bad days once I started to see Dr. Blair Grub in Toledo, Ohio. He is the best of the best of the best on POTS. He also has written many books. My symptoms of POTS have been under control since I saw him. Hang in there everyone, it will get better. It just takes time to see what meds will work for you and your body.
