>> what were the changes you said because the changes his body was going through? >> it was like michael was a hamster. could not sit down, could not rest, was restless and he cried and craved sleep. >> you said that actually this trial. let's listen to when you said he was like on a hamster wheel. in the video you have, dr. conrad murray talks. watch. >> so in michael's case, what he needed at night was not demerol, it was not propofol, excuse me. he needed to have demerol. but since his supply chain was cut from beverly hills, he was on his own. and he had never shared that with me. so i had no idea why it was so impossible to see michael like a hamster that night. couldn't sit down, couldn't restless, looked as though he was out of the movie "thriller." and i could not imagine that he was doing something like this.
