Narrative:
Aircraft a cleared out of hold with descent to FL280 from FL310, initial heading leaving pattern, clear of conflicting traffic at FL290. On course clearance put aircraft in conflict. I was relieving controller and established separation with turns and descent. Supplemental information from acn 507085: as far as factors affecting the quality of human performance. I needed to use the bathroom so badly that it was all I could think about.

Title: RELIEVING ZDC CTLR TAKES ACTION TO SEPARATE 2 ACR ACFT AS ONE DEPARTS HOLDING PATTERN IN DSCNT.
Narrative: ACFT A CLRED OUT OF HOLD WITH DSCNT TO FL280 FROM FL310, INITIAL HDG LEAVING PATTERN, CLR OF CONFLICTING TFC AT FL290. ON COURSE CLRNC PUT ACFT IN CONFLICT. I WAS RELIEVING CTLR AND ESTABLISHED SEPARATION WITH TURNS AND DSCNT. SUPPLEMENTAL INFO FROM ACN 507085: AS FAR AS FACTORS AFFECTING THE QUALITY OF HUMAN PERFORMANCE. I NEEDED TO USE THE BATHROOM SO BADLY THAT IT WAS ALL I COULD THINK ABOUT.
