I take both. 500-1000mg acetaminophen, 200-400mg ibuprofen. Usually helps for headaches which I get frequently. I only take them for the worst headaches though, so probably once every couple of weeks on average.

Yeah if I need to I take both also. In addition I be sure to have a caffeinated drink also as caffeine has been shown to both speed the absorption and boost the efficacy (5-10%) of paracetemol over a multi hour period. https://pubmed.ncbi.nlm.nih.gov/17442681/
