Hard ? Haven't been clean since 2018. I've learned to lower my usage and take minimum i needed to not be sick
You can say i'm a responsible addict. There's been times i've gone a day without and its a painful experience. Last year in October i thought i had weened myself low enough and had started micro-dosing tiny amount of Suboxone. "The Bernese Method" is what its called. Actually wife fiance at the time had read about it and she has successfully done it a few times. I myself have tried it and was successfully once. But it didn't last long.    With 2 people using and not on the same plan it is impossible to have a strong enough will. So, shes recently left me and i dont blame her. Even if she was the worse addict. 
also experienced precipitated withdraw. went without any fentanyl for 5 days and only took a small amount of Sub but didnt know fent stays in your bloodstream or Fat cells for weeks. That was painful. Was alone and called a ambulance to go to the ER. That was a year ago.
Its just on and off for 25 miserable years.. 
hope you can help..
