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.
Usually it will not go away the whole day. Only in the evening that it starts to subside. And when I decide to take it, I need to do it in a specific way. E.g. direct lying extremely comfortably, but not sleeping, or it won’t be as effective. Or drinking coffee in front of my pc. And a few other ones. I don’t get why but I usually just feel what specific ‘ritual’ works best for any given moment. Sometimes I guess wrong and the headache won’t disappear. This combination with coffee and adhd med seems to work best though.
