I don't think it's the presence of >helium as much as it is the elevated O2 on deco. I felt that I mostly licked my "feel like shit" problem by hanging below the ceiling shown on my Suunto Solution. Of course, that also slows down the rate that the Solution thinks I am off gassing at, so I wind up with both less deco stress by being below the ceiling, and more deco. More efficient deco gas seems to have the same effect. For DCIEM table 1S dives, I add a five minute safety stop to the deepest stop. Since table 1S only covers required stops at 10' and 20', I know that I cannot be significantly on gassing. I go by the assumption that "tiny bubbles" is real, but the empirical testing has all been done on Haldanean models. So hang deep to let them bubbles bubble out, and then do a full Buhlmann or DCIEM deco schedule. Wrolf -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
