the proper way to taper benzos is really fucking slow. this website goes into great detail about the process, it's a UK dr's site, with lots of experience treating dependent people

i reccomend all the main sections;
• Chapter I: The benzodiazepines: what they do in the body
• Chapter II: How to withdraw from benzodiazepines after long-term use
• Chapter II: Slow withdrawal schedules
• Chapter III: Benzodiazepine withdrawal symptoms, acute & protracted
a proper taper should have your heart rate up a couple beats for a week or so after dropping the dose a very tiny bit, without much w/d symptoms. this makes it less disruptive and allows your body to catch up with what's happening
if you can't taper fast or medium, quicker tapers are rough and hard (unless you run out, it's really hard not to take more when you're quite not yourself and feel like you may crack at any point) but there are drugs and behaviors that help. if you have a lot of motivation to quit, you might not have the time for a long taper (which could be anywhere from 3mo to years)
most hospitals do detox with a quick taper, a matter of weeks. often they don't taper you off benzos but give another drug that effects gaba transmission and then they taper you off of that (less controversial to give those to addicts i guess)
tapering/quitting is very disruptive, and habits that help like exercise, diet, showering, socializing, will probably be disrupted. try to get back on those as soon as possible so you don't lose the habit. i try to take my own advice but benzo/opie w/d makes things feel a lot more exhausting/taxing than they actually are
it's not gonna be easy and you won't feel right for some time. you're gonna get a big rebound of any symptom benzos helped alleviate. you have to really understand in your head that it'll get better, that generally people seem to have a lil less anxiety after a year off (tolerance seems to get to the point where paradoxical effects occur in many people, including me)
it can take up to 2 years for some symptoms to fully dissipate. it can take up to 1 year for them to calm down to very low levels. most symptoms take up to weeks or months to dissipate. all depends on dose and length of habit of course. the symptoms that last so long are the ones included in "post acute" w/d
