Something i got it sorted , and i want to share !! Ok last month i dive a wreck on 65m for 35minutes. I used Trimix 18/40 , nitrox 36 , and O2 on 6m. After a deep stop on 45m i moved on to33m where i switched to ean36. Although 33m doesn't sound much as a narcotic depth after 2 breaths my head started to spin like hell. I felt like being in a barrel rolling down a slope...i switched back to my bottom mix and stayed there for a while. , i stayed a bit more and i switch again on my deco mix at 27m the barel stoped !. I have learned my lesson...... I have a friend who works in a lab , i had him checking my deco gas... levels of Co2 where acceptable.. Trey suggested to add a bit of He on my deco mix and i did on the next similar dive i was fine. I wonder what caused so much narcosis at such a depth ? Could it be that i was tired all day long on board searching for that wreck ? So here im from now on i will switch on trimix 36/20 or better ill stay a bit more to my bottom mix and switch to 50/50 on 22m..
