"So everybody knows, I don't know that it happens," the hip-hop artist told MTV, adding he completely blacks out at the time.
"I go to sleep and wake up in the hospital," he said. "I don't feel anything. I just hope it stops happening."
The performer said he has suffered serious headaches in the past, but they don't usually come on in the moments before he has seizures.
He also said he is trying to follow the advice doctors have offered him on how to prevent seizures in the future.
