For the original poster, like the others said, cabin altitude is automatically controlled and is normally 4-5K feet (short flights) on up to 7-8K for long haul flights. Alarms go off between 8-10K, and the passenger O2 masks deploy automatically at 14K. Most folks would need to be well above 10K to feel sick while sitting down.
Also the pilots do not have a separate pressurization system...if you were sick, they would be too. Unless they were both high-altitude ultra-marathon runners or extreme mountain climbers.
