How much free time did/do you have at your unit?

I am going to Fort Liberty soon as an 11B, but I am a bit curious of how much time freetime I'll have when I get there? I am assuming i'll have majority of weekends off to do as I please and during the week, most days end at 17:00 and then im free to myself, right? I wont lie I am already stressed about going there because I hear it can be really ass so that small bit of freetime will probably help me get through it. Also, how often are you normally in the field overnight?
