I had this loud drumming in my head and it was LOUD just like a big ship going over - FARRRK - I dumped the loop and went to OC air bailout and sucked in pretty hard - not exactly sure for how long maybe 2 minutes but the drumming went away and I kept going up the line - trying to get a grip on my self - missed a couple of stops on the way but figured that if I was that dosed up on 02 then it probably didnt matter anyway - just needed to get shallow and up - just kept thinking to keep a grip, focus on the rope and get shallow so the bloody PP02 got lower
Blimey!
Very interesting, and glad you got away with it.
The loud noise - reckon this is the "Wah Wah" effect the deep air guys talked about?
