Narrative:

Flight, VFR, pdk (peachtree dekalb) direct to mem, at 3000 ft to avoid headwinds. I had been up all night with the flu and was more tired than I thought. The autoplt was on and was going direct via GPS. I fell asleep about 40 mi out and woke up 15 mins later over the airport. I did not know what to do or who to call, so I deviated to a lower altitude. I circled to the south of the airport, at which point I made a normal call to approach control 125.8 and received a clearance for runway 27 and landed without any trouble. I spoke to nobody about this incident. Approach, tower, or ground control made no comment to me at any time. Cause -- flying while ill and tired -- resulting in falling asleep. Remedy -- being more cautious about health concerns and not flying if needed.
