Whenever I take over the counter pain killers (e.g. paracetamol, ibuprofen) I always feel different, like relaxed and almost a little sleepy. I'm not sure if it's because of the relief of not being in physical pain anymore or whether they just have this effect on me.
I've looked it up online but haven't found much information on it. Is this a known thing?
Also just a disclaimer I only use painkillers on rare occasions for physical pain following the instructions given and as advised by my GP. It's just something I have noticed seems to happen when I take pain relief, usually for period pain. I also want to make it very clear that I'm not suggesting that pain killers affect mood and I obviously do not condone taking them for this effect.
