Hi Maggie, I am almost 55. Was diagnosed at 37 but, I think I was born with POTS. I have to say that now, after removing stress from my life (a difficult marriage) I am feeling much better. My doctor for 18 years encouraged me to get a divorce, finally in February, I got up the courage to face life alone. I am fortunate that beta blockers work well for me. I have over the years learned to deal with all of the bizzare symptoms, but lack of stress is the key. I have learned to just give anything stressful to God and let it go. Not easy, but I am stubborn. LOL. Dawn
