Yeah, the restless legs was awful for me too- by far the worst. That and the fever and chills!
I’d never experienced anything like it before so it was a real wake up call! I believe you can quit Dotty. If you have a week before your next prescription you’ll go through the worst of the withdrawals anyway. May as well stick to it and not waste any more of your time or health on codeine!
However, if you need stronger pain relief (than otc stuff) you may need to liaise with your GP for an alternative ? Otherwise, you may be stuck in a cycle that is out of your control. Xx
