Benzos can cause confusion, Add/Adhd, after long-term use. Maybe you need to have your thryoid checked and get on something for add/adhd.
your blood pressure is with in normal range, going to the doctor, even if it isn't your normal doctor is the best idea. Low blood sugar can cause all of the above symptoms. It may be just a virus but its worth checking your sugar levels and full blood count to see you don't have any infections and such.
You may also want to get your serum levels checked to see that there is no build up of the drug in your system.
Let me know how it goes.
I agree with Shanoa. Go & see any Dr. at this point. Not only get your Blood sugar checked but also your adrenal glands as well. I almost lost a friend cause her stress hormones were extremely low. It also wouldn't hurt in getting the iron levels checked as well (shoot get everything checked). :-) (((HUGS))) hope this helps & I hope you feel better!!!
