Sometimes when doing negative dives in 5m deep pool, I lose air from my mouth to lungs via epiglottis (descending head first) and that makes me feel like I'm drowning right away. I can't equalize with Frenzel because there's no airspace in throat, and I can't exhale against my closed mouth becouse I have so little air in my lungs. So I got to ascend without hitting the bottom, and on surface it's hard to start breathing (hard to open epiglottis).
Is this caused by wrong kind of technique or just need of practise?
I haven't ever tried diving even to -5m with fully exhaled, always ~1/3 air left..
