****While sources close to Lil Wayne maintain he is fine & recovering...***TMZ continues to update:

3/18/13: Lil Wayne is still in rough shape ... and remains in the intensive care unit at an L.A. hospital 6 days after being admitted for seizures stemming from a suspected drug overdose ... TMZ has learned.

Sources tell us ... Wayne's condition has not improved enough to be moved out of the ICU ... and he continues to be monitored very closely by staff at L.A.'s Cedars-Sinai hospital.

We know Wayne has been surrounded by friends and family since he was admitted to the ICU this past Wednesday ... and we're told the mood around Wayne's bedside has been very serious.

Among Wayne's visitors -- Drake, Chris Paul, Nicki Minaj, Birdman and others.

TMZ broke the story ... Wayne's stomach was pumped at least 3 times after doctors suspected he had overdosed on the prescription drug codeine ... the main ingredient in "sizzurp."

Wayne has struggled with codeine for years -- and just a few months ago suggested he had quit using the powerful painkiller.

** if you missed how serious this story got, check out the updates from last Friday from TMZ: 3/15/13:

6:30 PM PT -- Sources at the hospital tell us Wayne is still in critical condition in the ICU ... but stabilizing.

We're told the prognosis is uncertain.

Wayne is sleeping right now ... which is odd, because he just tweeted saying he's OK and thanking people for the prayers and love.

5:16 PM PT -- Wayne's mother is currently on a plane flying to Los Angeles -- and we're told all major decisions about Wayne's health (including the decision to discontinue life support) will not be made until she arrives.

Lil Wayne is in ICU in critical condition after suffering yet another seizure, and we're told it doesn't look good ... TMZ has learned.

We broke the story ... the 30-year-old rapper was rushed to Cedars-Sinai Hospital in L.A. Tuesday night after suffering multiple seizures.  He was released Wednesday but just hours later one of his bodyguards found him in his room, on the floor and unconscious.

Wayne was rushed to the hospital again, but this time he did not stabilize.  He was taken to ICU, where he was placed in restraints because he was shaking uncontrollably.

We're told Wayne is currently "unstable," and has been placed in an induced coma.  He is breathing through tubes.

We're told several people are at Wayne's bedside crying, and a number of rap artists and family members are on the way.  Sources say the scene is violent as Wayne shakes uncontrollably.

Sources say there's evidence Wayne went on a Sizzurp binge after being released Wednesday, because doctors found high amounts of codeine in his system.

We're told Wanye's stomach was pumped 3 times to flush the drugs from his system.
