Is it worth it to take a benzo long-term if the dose is kept reasonably low?
no. the most i could see, while retaining therapeutic effects, is say a 1-2 month course once per year max. that would have helped me, but my doctor prescribed kpin long term, it's been almost 6 years now.
Will there be eventually simply no relief whatsoever from this dose, or will it just be a lot weaker?
mixed. paradoxical effects will eventually show up (for me, it took about 3-5 years). sometimes they will help, sometimes you'll be basically baseline, sometimes you'll have worse anxiety than you would otherwise.
Basically, I'm asking if benzodiazepines are a complete sham--simply create addiction--or if they indefinitely work in a therapeutic way once any "euphoria" or what have you passes in several months.
they're not a sham, they work. doctors just didn't know they stop working after a certain period of time.
Long-term, barring any continued abuse, might it work?
no. even taking the same amount every day for years, paradoxical effects develop. if you do mis-use it (take high amounts, try to cold turkey due to running out, etc) paradoxical effects will come quicker. the withdrawal its rather damaging to the psyche...
Could one simply be on it for life in the same way as heroin addicts in the United Kingdom are given their fix into eternity?
sure. i think a lot of people are in this boat, basically they are on benzo "maintenance". many of them might think the benzo is working, but it's placebo. many of the doctors might think it's working, too. i don't think the health care system really knows what it's doing with psychological illness.
many of these people are being switched to gabapentin, a "non addictive" "anxiolytic".
i'm confident that its "addictiveness" and withdrawal will be shown to be at least comparable (if not at the same intensity) to benzo dependence.
it often increases anxiety for me, and has other weird side effects, and i have only used it for a couple months, these aren't paradoxical effects. it's just a shitty drug for many people with anxiety. i feel like doctors are on just as much of a search for a "soma" for patients, as us users are on a search for our individual "soma"...
