not too much modern data i can get hold of to give you a definitive answer
i would suggest using somthing that was likely to have been used by the population back in 1930-40 when DNP use was widespread, and that would be aspirin. besides im nore comfortable using aspirin because acetominaphen (paracetamol...why the hell do you yanks have to call it something fsking different?!?) is removed by the liver, and depending on the enzyme pathway taken can result in a toxic metabolite. im not saying that this will happen, but its safer to just go for aspirin. heck you can swallow grams and grams of aspirin and still be ok
btw dont take aspirin if you are allergic, asthmatic, or have any stomach ulcers. an anti inflammatory cream like voltaren would be useful for you just now..
cheers
