Eric,

It was either you or someone else who said in another thread that one way to tell was to watch you adam's apple in the mirror and feel your abdomen: if your adam's apple moves when you're equalizing and your diaphragm doesn't, you're doing Frenzel, but if your adam's apple doesn't move and your diaphragm does, you're doing Valsalva.

Is that correct? I hope so, because when I read that I stopped going through your document as I realized that I'd always been doing Frenzel even though I'm not exactly aware of tongue movements etc.

Cheers,
Gordon.
