Has anybody successfully tapered off of lorazepam (Ativan)?

Has anybody successfully managed to successfully wean off of Lorazepam?
If so how was it done?
And if it was by way of switching to other drugs, were you then able to taper off of those entirely under a doctor's guidance?
My husband has been on Lorazepam for 16 years
He did well for 14 years, but dragged his feet about trying to withdraw while he was feeling better.
In May he had a relapse of anxiety, and insomnia, with brain fog, heart palpitations, and more.
Currently he's doing better, thinking better, but still feels like crap a large part of the time, can't sleep without the drug, can't nap.and still struggles with anxiety.
At this point, I believe it's the drug that is actually causing the problem. Currently he's doing 1 mg at bedtime and 3/4 mg when he wakes up at 2:30 am.
I know it takes 2 years for the brains GABA receptors to normalize after taking Benzodiazepines.
Also know it's really hard to withdraw, has to be done extremely slowly, and the side effects are exactly the same as the symptoms it is meant to help.
My goal is to eventually wean him off of all drugs as functional health tests show they block his nutritional absorption and may be damaging his intestinal lining. I would like to be able to repair his health using nutrition, supplements, and neurotransmitter amino acids.
All feedback is welcomed!
