In the only interview the couple is doing before their family is fractured again, Joe and Teresa Giudice opened up to ET's Jennifer Peros about how they will keep their family going when Joe begins his 41-month prison sentence.

With Joe's sentence starting on March 23, Teresa will once again be separated from her husband of 16 years just months after she returned from her 11-month stint in prison last year. While it's hard for the couple, it might be even harder on their four young daughters.

"Today the girls have got computers," Joe said. "They go on computers and they know everything. My daughter Milania tells me, 'You're going away for a lot more months than Mommy.'"

Teresa compared her time at the Danbury Correctional Facility in Connecticut to "living in hell," and she shared with ET the advice she has for her husband about how to navigate through his time behind bars.

"The biggest thing, I guess, is don't trust anyone," Teresa said.

Teresa also said she fell in love with yoga during her time in prison and she's been trying to get Joe into the practice before his sentence.

Despite the "horrible" conditions Teresa describes in her lurid tell-all, Turning the Tables, Joe told ET that he thinks the anticipation might be the worst part.

"I think that's the easy part -- going to jail," Joe said. "I think it's what they put you through before you go. As you know, they try to mentally and physically break you down, you know what I mean? So that's I think the hardest part of everything. I think going to jail is the easy part."

Teresa said that she'll make the hour and a half trip to see Joe at the federal correctional institute in Fort Dix, New Jersey at least once a week to see Joe, but their visits will be limited as conjugal visits are not permitted in New Jersey federal prisons.

"That's another stupid thing," Joe complained. "It doesn't make any sense!"

"I'm going to miss sleeping with him at night and cuddling with him," Teresa said. "I mean, he keeps me warm."

The couple's prison sentences stem from their convictions for conspiracy to commit mail and wire fraud and bankruptcy fraud in October 2014. They were allowed to serve time separately, so that one of them could be home to take care of their children.
