As far as short vs. long acting, every patient reacts differently. For example, I would recommend that you ask about clonazepam because on paper it seems to be a very desirable benzodiazepine. However, my personal experiences with clonazepam make me thankful for the wide variety of benzodiazepines available, all with slight differences in properties, half-life, etc. My body processes clonazepam in a weird way, as if it were a placebo. I can't feel a damn thing from it.
But don't let my subjective experience influence your own decision. Ask your doctor what they think might be best for you, in terms of long vs short acting. I would highly recommend trying the long-acting ones (diazepam, clonazepam) first, from what I've seen
in some patients, the shorter acting benzodiazepines tend to be more addicting, although this is my own personal observation, and I know plenty of people (who had no problem with shorter acting benzodiazepines) who ran into problems when they switched to longer-acting ones.
It's all about each person's individual body chemistry, so it's hard for us to say you should do this: _____________
Basically just be honest with your doctors, tell them your concerns about long-term dependency and that you only want to be on benzodiazepines for the duration of your detox (If you decide you want to use benzodiazepines at all during this time period) to avoid long-term dependency, basically trading opioid addiction for an even worse addiction, benzodiazepine addiction.
