'If I fell, lots of people fell ... it definitely was a lot of weight,' the 'Jersey Shore' star says about fears of letting his family down.By Gil Kaufman, with reporting by Sway Calloway Mike "The Situation" Sorrentino Photo: MTV News When you watch "Jersey Shore," you'll sometimes see its hard-partying castmembers wake up from rough nights out at the club with their hair disheveled, their rooms a mess and, if they're lucky, a companion in their bed. But in addition to headaches and fuzzy memories, "Shore" lightning rod Mike "The Situation" Sorrentino said he often woke up with the kind of hangover a glass of water and a few hours in the gym can't cure: deep regret. "That was going through my head every morning when I'd wake up," Sorrentino told MTV News' Sway Calloway in an exclusive interview in which he discussed his fears that an addiction to prescription painkillers could have cost him the friends, relationships and the budding celebrity he'd struggled to achieve.
