I am 47 and got pots 10 years ago.It hit me like a mac truck. I was bedridden for 5 years and housebound another 4. I had a severe case of pots and in a wheelchair. I can not take beta blockers or Florenf as they and many drugs trigger my pots. I started a low carb diet a year ago and it made a huge change in me.I am no longer in a wheelchair.I can drive. I can handle noise and light now.My temors are no longer 24/7. However, I daily have to physically push myself and I got shopping...I sweat ALOT. If I eat sugar or flour I get very potsy. I still am dealing with a weak immune system,even though low-carb diet has helped that. I was wondering if anyone else has this problem of a weak immune system and what you do about it. Thanks, Heidi
