No Bathroom for Jailhouse Lawyers in Texas

I would like you to know, not to long ago this unit stopped offenders from being able to use the restroom during our session. I am in the law library every day up to 3 hour a day M-F without being able to use the restroom. But in this same building they allow offenders from GED, Cognitive Intervention, and Changes to be able to use the restroom. Its not right when you have offenders in the law library fighting criminal appeals, civil cases, grievances etc. and not able to use the same restroom the other offenders use who are not in the law library. Would you know if there anything that I could do to be able to get this unit to allow us to use the restroom without them ending our session?
