Narrative:
While on an IFR flight plan I was cleared direct to linden VOR then direct to har VOR at 21000 ft. I was alone in the aircraft and believed that I could relax and rest my eyes for a few moments while about 7 mi south of linden VOR. I didn't sleep for long but woke up to ATC calling me and found that I was 7 mi north of the VOR not having made the necessary turn towards har VOR. Although this did not cause a large problem I was not on course as cleared. The solution is to not intend to rest ones eyes until one is on the ground with the engines shut off.

Title: CORP SMT PLT FALLS ASLEEP AT CRUISE. OFF COURSE WHEN HE DOES NOT CHANGE HDG AT VOR XING.
Narrative: WHILE ON AN IFR FLT PLAN I WAS CLRED DIRECT TO LINDEN VOR THEN DIRECT TO HAR VOR AT 21000 FT. I WAS ALONE IN THE ACFT AND BELIEVED THAT I COULD RELAX AND REST MY EYES FOR A FEW MOMENTS WHILE ABOUT 7 MI S OF LINDEN VOR. I DIDN'T SLEEP FOR LONG BUT WOKE UP TO ATC CALLING ME AND FOUND THAT I WAS 7 MI N OF THE VOR NOT HAVING MADE THE NECESSARY TURN TOWARDS HAR VOR. ALTHOUGH THIS DID NOT CAUSE A LARGE PROB I WAS NOT ON COURSE AS CLRED. THE SOLUTION IS TO NOT INTEND TO REST ONES EYES UNTIL ONE IS ON THE GND WITH THE ENGS SHUT OFF.
