@JoeJoe the first thing I would say is it depends on what jail and what state you have to go to. I know some county jails around the US can be pretty tough, but I will say they should be separating the violent inmates from the non-violent. I had to spend 4 weekends in jail and I wrote all about my experience here in Texas. https://dui.zone/weekend-jail-time-in-denton-county-texas/
I would first ask your attorney if weekend jail is an option, or even a work release program if you have a job. With weekends, you check in Friday evening and out early Monday morning and it counts as 4 days. It’s an option I had because the work release hadn’t opened after covid. The work release program usually means you are released early each weekday so you can go home, get ready for work, and continue working your job. Then you go back in the evening. You spend the night at the jail and get 2 days towards your time. Your attorney would be able to confirm if they have these options available. The weekends were a great way for me to break up the 15 days and you basically are there the entire day half of the time.
But I suggest reading my experience. It might ease your mind.
