Poor Pivs… we reported earlier that Jeremy Piven dropped out of David Mamet’s Broadway production of Speed the Plow, citing high mercury counts. Now comes news that the mercury poisoning was due to sushi and Chinese herbs.

Jeremy Piven’s doctor has given Entertainment Tonight more details, saying that Jeremy Piven began experiencing fatigue and neuro-muscular dysfunction late last week.

By Sunday he was feeling dizzy too.

Jeremy Piven has been known to eat sushi regularly, sometimes twice a day, and has been taking Chinese herbs. Both of these things could have contributed to higher mercury counts.

Jeremy Piven’s doctor said Pivs will come out of this alright: “He is going to be OK. This is completely reversible… He just needs to really lay low and rest.”
