Lil Wayne -- 'I'm Good' ... After Double Seizure

Lil Wayne says he's all good ... despite suffering from two seizures in the past few days which left him hospitalized until yesterday evening.

Wayne tweeted just moments ago, "Thanx for all the prayers! I am good."

TMZ broke the story ... Wayne made an emergency landing over Texas in his private plane Thursday after we're told he suffered a seizure mid-flight and was admitted to the hospital. Then, on Friday his plane made another emergency landing over Louisiana after he suffered a second seizure.

He was released from the Oschner Medical Center in Kenner, LA Friday afternoon (below).
