Bush Taking Anti-Depressants to Control Mood Swings

...President George W. Bush is taking anti-depressant drugs to control his erratic behavior, depression and paranoia, Capitol Hill Blue has learned.
The prescription drugs, administered by Col. Richard J. Tubb, the White House physician, can impair the President's mental faculties and decrease both his physical capabilities and his ability to respond to a crisis, administration aides admit privately.
"It's a double-edged sword," says one aide. "We can't have him flying off the handle at the slightest provocation but we also need a President who is alert mentally."
Tubb prescribed the anti-depressants after a clearly-upset Bush stormed off stage on July 8, refusing to answer reporters' questions about his relationship with indicted Enron executive Kenneth J. Lay.
"Keep those motherfuckers away from me," he screamed at an aide backstage. "If you can't, I'll find someone who can."
Bush's mental stability has become the topic of Washington whispers in recent months. Capitol Hill Blue first reported on June 4 about increasing concern among White House aides over the President's wide mood swings and obscene outbursts.
Considering there is information that Gwb is drinking and most likely still on anti-depressants (maybe even heavier due to the pressures of a severely damaged presidency). There is a lot of reason to think the guy probably has little clue where he is or why.
He must have had an interesting psychodelic experiance riding around New Orleans in the truck with the sights, smells and motions.
