Hi
I am experiencing exactly the same problem. The same thing applies to my niece and to my daughter. If I think of it, I start getting the urge. I have the need every day but normally only a few times per day. It gets bad when I run; then I need to stop or slow down, breath deep and if I "succeed" I can increase pace again until a few minutes later I need to do it again. I have had it my whole life. I am 47 today. Only my niece had it investigated thoroughly at a doctor. She suffers from sinusarytmi.
