Codeine - how much is too much?

I've been on 60-80mg for 3 days, taken roughly every 6 hours and starting to get some bad effects. I need it for pain but the shivering, anxiety, stomach pains and nausea when I go without it are getting worse. I don't want to get dependence on the stuff.

codeine sucks

For pain it's good. Similar to morphine in high doses.

Codeine is synthesized to morphine. It sucks though. But you're not anywhere near a big dose so the side effects you're having is just a bad reaction to codeine, period.

"When you go without it"? But you're taking it every 6 hours . . . when do you 'go without it'? You mean like a few hours before your next redose? That's just the side effects of codeine, not addiction. You're also taking a very normal amount. Just don't ever raise it, and when you don't need it anymore, stop.

I bet some of those symptoms are from all the APAP in the pill as well, like the stomach pain.
