Dr. Conrad Murray : I'm Rail Thin From Explosure Diarrhea "WTF"

Dr. Conrad Murray has dumped 30 pounds because he's pooping out his guts and he blames the water at L.A. County Jail .

Sources said Murray has been extremely sick since becoming an inmate last November . He claims the water smells and tastes bad , and believes it has given him a horrible case of dynsetery . Murray says the bad water , along with a bad diet , is ruining his health .

Murray says he can't eat jail food and is force to eat what he call's 'cat food' which he buys at the commissary .

Murray buys canned tuna for $4.25 a pop , salmon flakes for $3.50 and canned mackerel for $ 2.50 . Murray is telling friends that aside from cats , he's the only human being forced to eat canned mackerel .

Sources says Murray is filing multiple appeals to get out of jail . Primarily , because his health is compromised .

L.A. County Sheriff's spokeman , Steve Whitman says ... "All inmates receive the proper nutrition and medical care that is required by law , but the Sheriff's Department goes above and beyond what is required .

We don't know how the appellate judges feels about diarrhea , but one thing we know for sure ... jail is really a sh**ty experience .

Well Conrad ... no hard feeling ... that's just KARMA ! Just sayin' ...HeHe
