Scott Disick went back to his partying ways this summer while filming "Kourtney and Khloe Take The Hamptons." After being hospitalized for alcohol poisoning, the reality star agreed to stop drinking until girlfriend Kourtney Kardashian gives birth to their third child. Disick only drank water while hosting Liquid Sundays at Connecticut's Foxwoods Resort and Casino while co-host Khloe sipped on champagne.

"I'm excited to just be feeling good and living healthy, eating better, exercising more and doing whatever I can to get by," he told PEOPLE. "I'm good."

"I've had ups and downs. Every time you can better yourself it's a good thing, and a positive thing."

However, partygoers told Radar Online LD appeared to be "miserable."

"Khloe was upbeat and friendly, but Scott looked totally and utterly miserable," a source told the publication.

"He was not in the mood to talk to anyone, and just seemed so uncomfortable. He held a bottle of water in his hand for the entire party."

Perhaps if he was able to drink, Disick would have felt more in his element.

"The pool party was totally crazy," the source continued.

"There was alcohol flowing everywhere! People were falling down drunk, and girls went in trips of two or three to the bathroom."

"It seems very strange that someone who wants to stay sober for his girlfriend would surround himself with booze and party girls."

This comes on the heels of reports multiple members of the Kardashian/Jenner clan need rehab.

"Kris is unraveling. She can't deal with everything that's happening in her life," an insider revealed to In Touch.

"She starts drinking early in the day and is often out of it by sunset," they added.

Jenner is allegedly "drinking in excess," recently switching from wine to vodka for fewer calories, and children Khloe and Rob Kardashian and Kourtney's baby daddy Scott Disick are following in the momager's footsteps.
