Wow its lovely to see all you guys stepping up to the plate and getting this awful drug from your lives!
I am about 6.5 weeks and honestly feel so much better! I was taking between 24 to 32 Nurofen per day so about 400mg of codeine. The last 3 years was much less than previously but even so the WDs were horrible and lasted about 3 weeks I would say. Just putting one foot in front of the other and self care really helped me. And I am glad to not be chemist hopping any more.
Celtic, the mental side is horrible but its not a given you will get cravings although you likely will. Read as much as you can for inspiration and talk. You definitely are not alone!
