Narrative:

On departure, we missed a waypoint on the climb out. The FMC automatically loaded its own route. I verified the route with the pre departure clearance and then went to preflight. The captain had yet to arrive when I left. When I returned, he was proceeding with his setup. He chose to fly first. We departed using LNAV to fly the departure. While leveled at 6000 ft, we received a TCASII 'traffic' alert. The controller advised us of the traffic which we had in sight. He then asked us if we were on a heading and we told him that we were flying the departure. The captain rechked his manual and found out that 2 waypoints were missing from the FMC. We quickly reloaded the FMC and got over to our route. Nothing more was said to ATC. What I found out later was the captain was suffering from seasonal allergies. He told me he was out of medication to treat them. Also, he had a tooth pulled a week ago and the socket became infected. He called in sick for a trip prior to our pairing, but because of scheduling's mentality on sick calls, he was afraid to call in sick again for fear of retaliation. He also later told me he got into the cockpit and reloaded the departure manually while I was out preflting. This captain was not thinking clearly and had no business flying airplanes in his condition.
