It's interesting because my wife has been using Ibuprofen for headache relief, whereas I use Paracetamol. I usually got Paracetamol growing up but recent studies showing adverse effects of Ibuprofen on male fertility solidified my resolve and consistency in choosing Paracetamol. My wife's reason for using Ibuprofen was simply because it worked better for her. Now it's kind of surprising to learn that Paracetamol has negative effect on women's fertility... I guess this means that both drugs are harmful to a different gender? What a coincidence? We were both using the optimal one for ourselves for reasons beyond our understanding... Until more data comes out.

Anyway, I understand arguments for avoiding drugs, medicines and chemicals altogether. Clearly, everything is more complex than it seems and side effects can never be fully known or understood; especially on a case-by-base basis given that everyone's DNA is different and responds differently to chemicals. I only take Paracetamol if I have a migraine with visual aura which is quite rare. I don't take it for standard headaches.
