My father was prescribed Valium before it was controlled, in the late 60s, as he worked swing shifts at a mill and could not sleep. We had a local doctor who got many of our town people hooked back then.
My father was addicted for 20 years, way past his retirement. He was forced off Valium around 1988 as no doctors left would prescribe him any and the last 4 years of his life were terrible. He tried every anti-depressant available at the time and nothing worked. He could not sleep, had terrible leg aches, would keep my Mother up rolling in the floor, walking the floors (we know so much more about PAWs than back then) and really never got better.
When he passed at 70 in 1992 from lung cancer it was from smoking 60 years, but I hated that the last few years of his life he was so miserable.
Please try to get off Valium in whatever method works for you while you are young, as you appear to be. Your chances will be better now than later of recovery.
