Unfortunately, drug addicts have ruined it for people like yourself who have a legitimate need for these pills. A pretty well written show that gives a good insight into all of this is Nurse Jackie. It opened my eyes to the problem of addiction.
I have a stash for Lorazepam from a few years ago. I think it has actually expired. Apparently I have the opposite luck. I went to the doctor because I had a pretty serious cold and would be flying for work ... I wanted something so I wouldn't have sinus issues. I don't know too much about medications and such so they wrote me a prescription for this. It wasn't until after I learned what it was. Never used it ... didn't take them with me.
