yes it has its uses for anxiety off label. it's a godsend for opiate WD. But they give it to hyperactive kids, ppl for opiate detox, anxiety. So yea, its a pretty useful drug to have around.
Yes. Works very well for opiate withdrawal and helps with stimulant comedowns. Can be very sedating though, some find that it is best to use at night only. It also can cause rebound problems when taken for awhile.
