I detoxed cold turkey from heavy long term(over 2 years) benzos.
On the 10th day there were severe hallucinations with a disorientated catatonic like state and more serious physical symptoms. 911 was called and I woke up in the hospital where the Dr. put me back on klonopin. The ER Dr. said the benzo detox was too dangerous, especially cold turkey. The medical professionals at the treatment center later told me about the second detox at 10 days where there can be another intense physical benzo detox episode.
If a person is being tapered off benzos this type of intense detox is less likely.
Definitely follow the doctor's advice.
