Vomit goes thru regulators pretty darn well. Although I did take it out after to wash my mouth and it out.
Still not sure why, was on 36% at about 102feet which is close to the limit for oxygen toxicity. Might also have been the 8 foot swells on the ride out.
Got to take a long ride out of Islamarada with a Dad and Lad who had a bag of Burger King they plowed through as we shoved off. Made out into rough seas to reach our spot. Every one was green by the time we got there. I geared up and hopped in to settle my stomach, and after quick check rose to surface and saw all hands looking aghast at me while Dad and Lad were hanging over the side. I came up in the chum slick dead center. Cleared my reg and dropped. No worries. Was a tad tart tasting...
