Riluzole, has anyone tried it ?

I'm focusing on pain, Neuropathic pain(inflammatory) and spinal cord related pain but I'm reading several things about how this drug works on glutamate transporters, imbalance between exitatory and inhibitory system and others, also for cancer, ALS, and to improove

forms of  neurodegeneration

have anyone tried it and has some feedback to provide?

took the first 25 mg today, no issues, I'm suspect to speak of it, felt a slight effect of clarity, let's see if it will be of help with pain and mentally, I'm tapering pregabalin and on other drugs for inflammation and overall damage..
