In brief: Probably 16 hours
Normal humans can probably go about 16 hours without sleep before their brains and bodies start having unusual symptoms.
If forced to stay awake, people can probably make it to 36 hours before extreme sleepiness sets in, but they will be acting a bit strangely. It is hard to imagine one making it past 48 hours without training and conditioning to purposely stay up longer.

This then means what I have long suspected we Doctors are not normal humans, we are abnormals.

In brief: 24-48 hours
Once an individual reaches 24-48 hours without sleep, they become mentally, psychologically and physical irrational, irratic and unstable.
