Yes. Heinous. I hope your son is 'ok.'
This issues is (was) taken seriously by some people... Heather Ashton principally - benzoinfo.

Whoever allowed this doctor to remain
ignorant of,
or uncompliant to,
hopefully developed and mandated protocols... is culpable.
That IS torture.

Why is it even legal for doctors to cold turkey any long term user? Now we have the issue of finding Benzo as Drug stores. only so many benzo's are allowed to each pharmacy.
Years ago I suffered for 6 mths after an attempt was made to stop my Valium in 3 days. Day 1 my heart rate, blood pressure went crazy so was admitted to the hospital. I couldn't hold i throwing up, having tremors, seizures at day 2. Day 3 a nurse comes in the room to inform me he had no benzo at all for me on day 3. The nurses weren't trained, didn't know what to expect and told me that. I got in my purse took a low mg benzo, made an appt at families inc. A specialist there, starting helping me. He gave me klonopin and seizure meds. Lots of therapy! My family doc. Left me laying in a hospital bed and he or nurses having no knowledge of how to treat me.
It took 6 mths of throwing up, tremors, I couldn't leave my bedroom. In and out of the ER for fluids. Lots of nausea meds, sleeping, and only leaving for medical attention. Losing 60 lbs at about 35 yrs old. On disability within 5 years. It ruined my life. Now I have to worry my drug store won't have my meds over 20 yrs later. So I have over 35 yrs of being perscribed benzo. I already know cold turkey don't work. But who helps me when I can't find a drug store. I have severe anxiety and panic disorder. A slue of health issues. My fear is its gonna kill long term users. I've worked on cutting down. Very slowly but with bi- polar disorder, I cant calm myself. So start my regular dose to get through a maniac episode. How will I deal now at almost 59 yrs old. Who is fighting for the people who face possible death when there are no pharmacies with their script??? What happens to patients who either take benzo or try to survive non stop seizures for hours? I'm not healthy enough to go through that!

I was tortured too.
