Clonazepam has helped my nervous system too but can't be used regularly without tolerance. : ideas for alternatives: any safe nmda antagonist --ketamine, memantine, xenon (expensive but safe)... iv or injected magnesium (more mild but worth a try), progesterone (
@Hip has it in his nmda antagonist thread ), maybe taurine ...
Now for other things besides nmda antafonists that will do similar things to benzos wrt gaba/glutamate, if not acting by exact same mechanism: gabapentin or Lyrica, more subtle but still... some help. Phenibut: almost same level of dependence induction as clonazepam , probably not quite as bad I took it twice a week at full, high doses, for literally a whole semester of school with no withdrawal issues... phenibut has more effects on gaba b than a, unlike benzos, and it's got gabapentinoid effects, it affects cognition way less than benzos, you can be very lucid on it.
Kratom will help a little bit bc of nmda antagonist combined wjrh partial opioid agonism... the dependence caused by kratom is real but nowhere near as bad as benzos , but if you get stimulant strains it can mess wjth your pots. Opioid agonists lower glutamate indirectly and thus help with that brain on fire feeling that benzos are helping with...but kratom also has nmda antagonist properties, which makes it sort of like killing one bird with two stones??? Lol ... by which I mean using two things to do one thing at the same time pharmacological.
Imidazenil is something which could be very promising for me/cfs and for helping people with benzo dependence problems which can be hell, it's a drug that affects gaba and I believe agonized gaba receptors without causing upregulation or tolerance
On a note of more mild things, I really think that everyone should try California poppy. Not an opium poppy, it just has the same name, and is more a mild sedative without opiates in it, which has properties similar to benzos without the intense dependence, and more mild. It doesn't cause the possible liver problems that skullcap and valerian can.
Although if u don't have liver problems and don't take tylenol or drink I'd recommend skullcap and valerian
I hope this list of things helps
Gaba/glutamate imbalance is indeed one of the main issues in me/cfs but I would not recommend taking benzos more than once a week or even less. Whitney takes them I believe once a month. As far as I know taking them once a week it's almost unheard of to develop tolerance, but once a month even more so... like that would be genuinely unheard of.
For people already dependent on benzos things can be pretty bleak, although Italian doctors have a method for getting people off using flumazenil, a benzo antagonist. Which sounds insanely dangerous , but studies show it works , tapered up from very small doses.
Flumazenil is not something anyone should try at home though. I may go to Italy for that if I can ever be well enough to travel
