I’ve experienced it from a rehab nurse’s point of view. But these were mostly long-term addiction cases. It has the intensity and symptoms of heroin withdrawal, both psych and physical, but instead of lasting three days to a week, it can take up to four weeks. It’s hell and few people can get through it without medical assistance. And because of this, insurance policies that offer rehab reimbursement, often won’t cover benzo withdrawal treatment. It’s too damn expensive and the problem of benzo addiction is too common. Basically, a benzo addict without some wealth is SOL in America.
