I am surprised that no one discusses LDN, Low Dose Naltrexone. I have used Naltrexone for a few years for complex pain and impulse control, the results are impressive. I do not require APAP (Tylenol): nor do I know of a doctor that would recommend that you take it. Here is a journal from 2021. I am not a doctor but avoid acetaminophen, which is well beyond overkill. All that Tylenol does is destroy the gut wall and liver.

Naltrexone is an opioid blocker available since 1984. Liver failure is exceptionally rare, far more common in the atypical olanzapine, which is almost guaranteed. Naltrexone toxicity occurred, of course, in those with shot livers (drunks and junkies). What do you expect?
I do not understand the sleep disturbance. My sleep score averages 88, which is good. I have panic disorder. Naltrexone does not foment anxiety. If it makes you tired, please inform me. And, Naltrexone aids in reducing all forms of headaches. You can use synthetic analgesics: I can take up to six, 50mg Tramadol per day, with Carisoprodol.
