I've actually experienced all three of these.
Currently I take Restoril for sleep every night, and I have yet to try and fall asleep without it even though I said I will. So it's possible I don't need it anymore anyway..
My first benzo prescription was for Xanax prn and one other time about 4 or 5 years later.
My last pdoc was against prescribing them which is why he gave me Vistaril prn for anxiety. He did prescribe me klonopin strictly for 30 days because I had such a hard time after the death of my grandmother, I couldn't get anything done. But as soon as those 30 days were up, I was on my own.
