I'm not on any other medication cos my anxiety is usually manageable, but I had a bad day. 

In the end I gave myself a headache from worrying, so I took a tylenol cos headache. 

It reduced the headache but I also felt my anxiety reduce massively. It was the recommended dose and everything but within about half an hour I was relaxed and functioning. 

Do you think this is a side effect of just having the headache go? Do you find Tylenol or other paracetamol based medications reduce anxiety?  I tried googling but I didn't get much.
