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.
I see! I thought about this as well. I was indeed also worrying whether this itself had any (unforeseeable) side-effects. Hmm, just a fancy amino acid? I hope this is indeed as innocent as it sounds.
