I have never taken NP,I can take 4 c 30mg of Dihydrocodeine so I have no idea how many NP equates to 120 mg of codeine, I am guessing quite a lot
Like you I now take the stuff just to feel normal .The euphoria is long long gone
I wish I could answer your questions but as an utter failure myself I cannot
I will be thinking of you tomorrow when it hits but this time next week you could be well on your way to this nightmare being over
Be as strong as you can be
Best wishes to you
