I had a moderately bad headache earlier today , but had run out of ibruprofen and paracetamol. I found some codeine in the medicine cabinet and took 2 30mg tablets. Within 20 minutes I was sweating, feeling numb , dizzy with tingling sensations on my teeth and felt very nauseous. An hour later, I still felt just as bad and then started vomiting almost constantly for around 20 minutes. I then fell into a deep sleep for several hours. Has anyone else ever reacted to these tablets like this? I'm usually tolerant of most medications but this was awful. I'm better now, although still a little tender from vomiting so much.
