Narrative:

I was jumpseating home from vacation. Approximately an hour after takeoff; the captain asked me to come forward and indicated that the first officer appeared to be in physical distress. This was indeed the case; in a span of 2-3 minutes; I witnessed 2 periods of incapacitation/non-responsiveness from the first officer with each episode lasting approximately 20-30 seconds. The first officer was also sweating profusely. I assisted the first officer from the operating seat to a jumpseat and gave him water. I then occupied the first officer seat (I am a qualified captain on the aircraft) and assisted the captain in a divert to the nearest airfield. We were met by emt personnel at the gateway.
