Lil Wayne Drank 'Massive Amounts' Of Lean Before Seizures

Lil Wayne likes to blame his seizures on his epilepsy.

But his lean issues probably contribute to them, too.

Wayne was in Milwaukee for a club appearance the night before his latest midair incident.

Club-goers spotted Wayne walking around with up to five bottles of Promethazine/Codeine syrup. One onlooker told TMZ that Wayne pounded three of the bottles on his own.

Wayne has said he quit lean because of his seizures. But he's been spotted double cupping it many times since then, including Sunday night in Milwaukee.

Wayne was hospitalized yesterday after his latest seizure. He is listed in stable condition and is said to be in good spirits.
