Back in the days I started researching gabapentinoids and GABA Modulators (mainly loads of benzodiazepines) like clonazepam, diazepam, lorazepam or other alprazolam and I've to say that benzos with strong anti-convulsant effects are more reasonable option to choose from than intense anti-anxiety effects that alprazolam provides. I also considered a highly addictive potential of short, medium and long-acting benzos. These long acting ones like clonazepam or diazepam are safe to use in moderation - up to three times a week. Despite using benzodiazepines since 2019, I did not experience any withdrawal symptoms but the massive tolerance has unfortunately kicked in. According to benzo equivalence table, 4 mg of clonazepam represents 80 mg of diazepam - that's a very high dose for someone who did not use any drugs from this group.
How does clonazepam reduce tinnitus? It is related to GABA B agonism. :D It means, that all the signals and impulses from our CNS slow down.
Common effects of all benzodiazepines are drowsiness, anti-anxiety effects, being indifferent to anything that happens around, and sedative properties (depending on dosage). When it comes to addiction, tapering down the high doses of benzos is worse than alcohol or methadone / fentanyl withdrawal - as the people say - keep that in mind.
I used pregabalin for over a year - constantly. Pregabalin works completely different than benzodiazepines (it has something in common with calcium channels, but it is still a mistery for specialists). It helped a little, but I mixed the recreational doses of it with benzos. The pregabalin itself is not enough. Two biggest advantages of it are fast increase and decrease of tolerance and very interesting alternative for traditional antidepressants (mainly SSRIs or SNRIs).
For now I keep trying medical THC use (with CBD as well), and despite of versatility of cannabinoids I think, that it's not worth it...
I have Meniere's disease and a hearing aid helps a lot on a daily basis. I took clonazepam over a month ago - so it is not as scary as it seems. ;)
Take care.
