Yep, different meds work differently for different people!
While it’s worked great for my nerve pain, it didn’t do a THING for my husband when he blew out his back a couple years ago.
I’ve heard of other horror stories too like what you describe, but when it works it’s a good medication. I don’t LIKE taking it, but the alternative is worse for me...
It’s original use was as an anti-epileptic/anti-seizure medication, and I’d bet it can screw with one’s brain chemistry for sure, hence why it would make some people, literally nuts! Lucky for me, I was already nuts! ;) (Just kidding - I think! LOL)
there is good nuts and bad nuts...
my neuropathy is better controlled with a mild dose of a drug that releases dopamine...and a mild dose of steroids...
