I often take painkillers (acetaminophen aka paracetamol), but I’ve noticed that it’s much more effective if I take them TOGETHER with my ADHD medication (ritalin aka methylphenidate) + my morning coffee. If I don’t take them AT the same time, the painkiller is far less effective.
I do not exceed the maximum dosage of painkiller (1gram per intake, mornings), but alone this would barely suffice to kill my morning headache.
My hypothesis is that since the LIVER has to convert all three, I am effectively overdosing on either substance (painkiller or ADHD meds), and damaging my liver in the process.
Afaik constant use of paracetamol has most impact on stomach, it does something to the lining.
Or maybe that was ibuprofen?
Not a medical professional either way so
Edit: Root cause aside as people have already told you here, I would try CBD it might help and shouldn’t strain the body as much.
