"Reach for the stars, everyone," Sheen wrote Thursday on #winning. "Dogspeed, Cadre. Out."
The sign-off message was accompanied by a photo taken out of an airplane cockpit showing a bottle of Tabasco sauce on the dashboard. But one had to read fast because by Friday night the Twitter page in question was no longer available, the Chicago Tribune said.
Sheen used #winning for more than a year to vent, posture and philosophize about his full-throttle lifestyle and his angry public departure from the CBS comedy hit "Two and a Half Men." The crowd following Sheen in cyberspace reached about 8 million before Thursday's grand finale.
Sheen, who has landed a new gig on "Anger Management," seemed to lose his enthusiasm in recent weeks, the Tribune said.
Sheen told "Rolling Stone" he had been using #winning to declare victory at a time he was actually floundering in "quicksand."
"How does he consider any of it a victory?," Sheen said. "I was in total denial."
