LDN for sobriety?

I am dealing with PAWS after quitting opoids. I also have fibromyalgia. It’s been three months sober & I think I have severely messed up my dopamine tank. I have had all my labs taken and am on an antidepressant. I’m wondering if anyone has tried low dose naltrexone and has had it help them recover their pleasure centers? I tried the full dose naltrexone and it made me feel numb, I couldn’t feel AT ALL, and I was so depressed I was almost suicidal. Any help appreciated, I am desperate. Happy holidays ❤️🙏
