In quotes obtained by the New York Post newspaper's Page Six column, Roseanne said: "One guy got up and cooked a turkey and ate it - that was, like, four hours, if you think about it - and didn't remember it in the morning.
"And all the time that happens to me - when I go up in the kitchen and there's a whole box of Triscuits laid out and eggs cracked on the wall, cheese everywhere.
"I 'Ambien eat,' like how Tiger Woods 'Ambien drove'. It's a weird drug."
Last month, ABC president Channing Dungey said Roseanne "crossed a line that cannot be crossed" with her racist tweet.
Reflecting on the decision to fire Roseanne and cancel her sitcom, he said: "[The decision] was actually made very swiftly, and what I'm going to have to say is that it was nice that it was so clear to everyone that there wasn't a lot of debate and discussion about it. We knew what we wanted to do, and we did it.
"For us, we have had multiple instances with Roseanne, and certainly this tweet crossed the line that cannot be crossed, but it was for us a sense of enough is enough and something had to be done."
