Dina Lohan -- Fidgety, Sweaty, Mumbling During Dr. Phil Interview

Despite insisting she was completely sober for her big Dr. Phil interview, Dina Lohan appears completely out of it during the hour-long sit-down ... sweating, slurring, and fumbling her words through the entire thing.

You'll recall, Dr. Phil's people released a teaser for the interview last week -- in which Dina appears seriously dazed and confused -- but Dina insisted she had not been drinking beforehand, telling TMZ, "I don’t care what it looks like. I’m fine and I don’t care what anyone says."

Dina blamed the editing for making her look messed up -- but after the interview aired today, it seems editing wasn't to blame ... something just wasn't right with Lindsay's mom. She was overly emotional, anxious, panicked, and disheveled.

As the interview began, a jittery Dina repeatedly asks "Are we rolling? Are we rolling?"

Dina appears extremely uncomfortable throughout the interview. At one point, when Dr. Phil asks about Michael Lohan's alleged abuse, Dina abruptly asks to put a stop to the interview, claiming she doesn't want to be on camera.

She adds, "God, it's so quiet in here."

As we previously reported, Michael Lohan -- who participated in the interview -- says he's positive Dina was "wasted" during the interview ... which was taped at 10 AM.
