There are plenty of us on here with codeine addictions and plenty who have beaten it. You seem to have it under control, just remember, in a few more days you will be through the worse of it
Are there any exercises you can do going forward to help your back? I suffer from chronic pain, I’m a 29 year old male, been tested for all sorts and the doctors find nothing. They won’t consider fibromyalgia because of my sex/age but I’m convinced I have it. Codeine gets rid of the pain so I’m fully expecting that to be back soon!
