I took 2 paracetamol tablets this morning, then 2 hours later my head was still sore so I reached for the ibuprofen- didnt realise til I'd swallowed one that it was actually another paracetamol I'd lifted! So I've taken 3 paracetamol capsules within 2 hours. I hadn't had any earlier on in the day so I haven't exceeded the daily dose but should I be worried about that over dose?
