thanks all for this thread , and Hennie for the carrot tip. I'm a real newbie to freediving so this info is really helpful. I attended an excellent freediving clinic in auckland last weekend, only thing was i had sinus trouble and "tooth squeeze" at 20 m which kinda took the shine off my day especially since my nose was making lots of shark bait (blood clots). Well i'll try the carrots, and thanks to last weeks dive ive found 2 fillings that need replacing. I'm not sure what hurt more tooth squeeze or the impending dentist bill.
