amantadine, any input?

i'm trying it for pain, lascinating nerve pain  neurpathy and inflammation ,it's a pde1 inhibitor, dopaminergic, ,some info on the drug https://www.mdpi.com/2218-273X/9/5/191

I'm combining it with roflumilast a phosphodiesterase-4 Inhibitor,

 

this wasn't my goal at all, still after kindling I feel like having a painfull autoimmune/inflammatory mediated neuropathy plus lascinating nerve pain which is being unsustainable,

 

wonder if anyone has experience with this drug  or anything positive or negative to add

doesn't feel very nice to take it, not reved up, just strange and not pleasant,  I'm too sensitive after too much damage tho, I will take just 25 mg following day, will have to keep searching to find something to aid with nerve damage/inflammation and maybe an autoimmune neuropathy
