Anyone here got any advice onto how to stop feelings of lightheadedness when they occur (not so much if it occurs at home, more like when in a situation when you absolutely cannot feel that way (job interviews, in a crowded shopping precinct, on public transport)).

I know to eat sufficiently but apart from that are there any physical things you can do which offer immediate relief from this and still don't attract attention from the public when you administer them?

In a job interview for instance when eyes are on you its got to be something you can do which will generally go unnoticed.

Please help guys!
