Avoiding codeine dependence?

First of all, please don’t tell me to seek medical advice from a doctor. I am in a foreign country and I do not easily have access to this. The first person to scold me for seeking medical attention on the internet will get a fishslap with a giant trout.

That said, I have been in daily, constant pain for over two months. I recently discovered that you can buy ibuprofen with codeine over the counter in the UK and had someone bring me back a couple of boxes. I’ve tried all the NSAIDs and they have not helped one bit, but one dose of codeine a day takes care of the pain for nearly 24 hours.

I realize that codeine is an opioid and therefore physically addictive. I am being very conscientious about trying not to become addicted, simply taking enough, when needed, so that I can go through the day comfortably.

Some days, I don’t need to take it at all, but when I do, usually I take a dosage of 25.6 mg once a day. Should I worry if I’m taking this dosage multiple days in a row? I haven’t seemed to have any withdrawal symptoms when I don’t take it for a day or two.
