I have only ever nodded off once. Was during a lecture on fire and maneouvre and we had roughly 2 hours sleep the night before - finished a 9mile load carry (which did serious damage to me but by the time I'd realised there was no safety wagon so just had to finish) at around 0300.
Wet and dry is really horrible, seen guys just refuse to do it and quite a few tried to quit next morning but weren't allowed to
Did it at around 20:00, then had to make a bivi without using trees, despite the fact we were beside a forest. Not one person had bivi poles. Took us 40 minutes to find decent enough sticks etc and it was terrible bivi - a bergen at each end and barely a stick to prop it up!
