Over reaction to paracetamol

This morning I slept an hour and a half past my usual waking time and when I woke I felt as if I had been heavily drugged, my mind was not so much foggy, as in deepest smog. This feeling is gradually going, but as I write (12.30) it is still there. While I was sleeping in DH got up, wandered round the bedroom, and, he says, I didn't stir and was deeply asleep. He was beginning to get worried by the time I finally surfaced.

I was so fogged up I forgot about a hair appointment that has been at the front of my mind all week.

Trying to work out what caused how I feel today, I began to remember that this is not the first time this has happened to me over the last, say, six months, but none as bad as today.

I then remembered that last night my hip had been aching and it woke me, so sometime between 1.30-2.30am, I so got up and took a couple of paracetamol.

It was only 2 and I have not taken any, day or night, for at least the last fortnight, so no question of taking too many or too close. My memory then suggested that the previous periods of fogginess could have been associated with taking paracetamol.

I was just wondering whether anyone else here has had this sort of reaction to paracetamol and what they did.

I have a history of over reactions to drugs. I am allergic to penecillin, and anti-histamins have exactly the kind of effect on me I think paracetamol is now causing.
