Note: not a doctor, also I think daily use of benzos is incredibly dangerous.
Just a few observations:
#1 "shotgun approach" and binge doses are generally
much worse for you neurologically than taking a small, steady dose of a benzo on a regular basis.
#2 using Valium PRN was moderately effective when I was in spike mode in making me less crazy. Taking Clonazepam + Gabapentin daily has,
so far been moderately or more effective almost 24/7, with my only "bad spikes" very much corresponding to personal periods of fairly extreme stress. I am only 3 years into this experiment so I will have to get back to you in another decade, one supposes.
#3 as dangerous as benzos are, I am going to put the risk of "using a benzo daily in the prescribed manner under medical supervision" as being much lower than "consuming aquarium chemicals that were not designed for human consumption and therefore may contain a lot of trace toxins that would not be allowed in something that is"
If you are continuously getting worse, there's something up
I mean, not necessarily? Sure, there's plenty we don't know about heavy metals but they're notoriously hard to clear and do cause ongoing damage in some cases. On the other hand, hearing tends to degrade with age, this tends to accelerate from the mid-30s into the 50s, and simple organic worsening of hearing
can lead to worsening tinnitus in some people, even if it doesn't seem to.
Personally I would not be trying to chelate out chems potentially consumed in 2003, barring the input of an actual doctor who had some clinical reason for thinking this is useful based on some measurable thing. I say this not because I think heavy metals are especially well understood, but because chelating agents can be quite dangerous, and, even if they work, if you don't know what you're doing you are freeing trapped heavy metals into your bloodstream.
