Floyd Mayweather has finally cracked under the strain of prison life .. after only 12 days behind bars.
Mayweather, 36, was booked into prison on June 1 to serve a 86 day sentence for assaulting his baby mama in front of their children.
But narcissists don't do very well when they aren't getting the attention they crave.
In court documents, Mayweather's attorneys begged a judge to let Mayweather serve out his sentence in the comforts of his home. The lawyers cited his declining health, and called the prison sentence "cruel and inhuman" punishment.
Lawyer Richard Wright wrote that Mayweather's confinement to his cell for 23 hours a day was taking a toll on his championship physique.
The boxer's doctor expressed concern for his "dehydrated appearance," his lack of muscle tone and dry mucus membranes inside his mouth -- symptoms that can be caused by nervousness and plain old fashioned fear, which affects the appetite.
In other words, Mayweather is not drinking enough water or eating his prison meals due to depression about being locked away from his lavish, baller lifestyle.
Floyd says his doctor also "expressed deep concern for [Floyd's] health and explained that any lengthy period of time with an inappropriate diet, coupled with lack of regular exercise, will most likely lead to irreversible damage to Mr. Mayweather's physique."
Floyd's doctor also told the court he's concerned about Floyd's diet ... because he used to eat 3,000 to 4,000 calories per day ... and now, the doc believes FM is eating less than 800.
