This link is for nebulizer doses for an asthma attack. I don't know if I'm doing the right math(as they say) but it appears to be 1000mgs.Froome allegedly had 2000mgs. Having had a nebulizer dose it left me shaking and dizzy, not a pleasant experience. The last thing I felt like doing was a 5 hour bike ride.
