June 25 and 26 were definitely not g'days for John Stamos. The ER star exhibited bizarre behavior during an Australian publicity tour late last month. Stamos spoke to TV Guide to set the record straight on what happened.

On June 25 he appeared to slur his way through an interview with an Australian newspaper. The next day, while appearing on the popular Aussie talk show Mornings with KerriAnne, he rambled through the interview and made a series of obscene remarks and gestures.

Stamos arrived in Australia on June 21, at the end of a whirlwind trip that included stops in New York and New Orleans, a vacation in Greece with his former Full House costar Bob Saget, a publicity stop in Japan, and a layover in Cairo before finally landing Down Under. "By the time I got to Australia my body was so out of whack," Stamos tells TV Guide. He went to a Sydney strip club his first night there. "I couldn't sleep, so I went by," he says. "I stopped to sign autographs and I had a Guinness beer."

A few days later he was still fighting jet lag so "I took a sleeping pill at 5 in the morning, Ambien," he says. He was so disoriented when he did the newspaper interview, he says, "I did not know what continent I was on." Still, because he couldn't sleep, he continued to take Ambien, leading to the disastrous appearance on Mornings with KerriAnne.

One thing the 43-year-old Stamos wants to make clear is that he was not drunk. "I was not drinking. I did not drink either morning," he says. "I do not have an alcohol problem. I am not David Hasselhoff. This is not a pattern."

Stamos, who admits "it was a disaster," says he's learned his lesson from this episode. "Now I know that Ambien is an eight-hour sleeping pill so if you take it, you better get eight hours' sleep," he says. "Do not take it at 5 in the morning. I do not take it every night, only when traveling."

He also hopes his reputation is not tarnished, especially Down Under. "I really do feel bad. I hope Australia will give me a chance to redeem myself," he says. "I love Australia. My plan is still to retire there." - Reporting by Mary Murphy
