Mike 'The Situation' Sorrentino: I Had a Prescription Drug Problem

"I have voluntarily taken steps to get control of a prescription medication problem I had due to exhaustion," Sorrentino, 29, wrote on his website.
"I have spent the past several weeks getting treatment for this problem and recuperating from my work and appearance schedule. I appreciate my fans support and love you guys."
On Tuesday, his rep clarified that he was not in a rehab facility, but rather, was "at an undisclosed location for for much-needed rest and recuperation after his extensive production and appearance schedule."
It seems he's doing well, as just a few hours earlier in the day, an MTV spokesperson said the network had "no comment" about Sorrentino's state of mind, but added that they "fully expect and are looking forward to the entire cast returning for a sixth season."
