Lil Wayne says he doesn’t know what it’s like to experience a seizure … because every time he has one, he completely blacks out.

Wayne — along with his mentor Birdman — sat with Sway from MTV and explained how his seizure episodes always strike without warning.

“So everybody knows, I don’t know that it happens,” … adding, “I go to sleep and wake up in the hospital.”

“I don’t feel anything. I just hope it stops happening.”

Wayne says he’s struggled with headache issues in the past … but he hasn’t experienced any head pain in the moments before the seizures strike.

Wayne has suffered multiple seizures over the past few months … and was hospitalized for several days in L.A. in March after a series of very serious episodes.

Weezy says the doctor has given him some tips to stay healthy … and so far, the rapper says he’s following orders.
