it doesnt really have a pattern, sometimes when im just standing doing dishes or doing paperwork at work... i went a few years ago and they had me do all kinds of silly things, jogging on the spot, star jumps standing up and siting down quickly whilst monitoring my blood pressure, and blood tests were taken but nothing ever came of it, everything seemed fine they said...
ive noticed that it happens more when im dieting, no matter what diet, it was really bad when i was on lipotrim, total food replacement,
maybe i should go back and see the quack, whats your diagnosis?
