BIRDMAN says LIL WAYNE only suffered ONE seizure, and it was not caused by an overdose of Sizzurp, or any other drug. He says, quote, "To me, it's just how he works. He works around the clock...he's just a hard grinder for this music. But it wasn't nothing about no drugs. He just needs to get some rest and relax." Wayne was released from the hospital late last night.
