Yes, apart from Diazepam in small doses, for leg and back spasms. I'm using cbd instead of (variously since 2012) amitriptyline, pregabalin, gabapentin, tramadol, naproxen, co-codamol.
The isolate doesn't affect me at all, apart from the sleep probs. Full spectrum is a little different, can make me feel a tad hazy, but not every time, it depends on the state of my mental health on a day to day basis, depending whether I'm proper depressed, just a low mood, or anxiety, or just trying something different for my pain.
Codeine worked for me (30/500 co-codamol)) but after a few days on it I couldn't shit for a week or longer, had all manner of stool softeners and laxatives, nothing really helped. The term I believe is fecal impaction.
Same as really, my lumbar spine is knackered, if after you've tried the free sample / other cbd's and want to try my cbd I will make a 10ml bottle up for you and send it to you, I've been using the same brand for vaping since 2016, was called Satijah Original Hemp, is now branded Harmony.
