@Krumple,
It is one thing to desire sobriety and it is a completely different thing to maintain sobriety, somewhere between the two lies the powerlessness.
If quitting was as easy as simply saying it, it would not be called an addiction.
The point is some people have tried and failed many times and when the disease progresses it kills people.
You seem oblivious and all you want to do it stroke yourself and say I did it myself. Well good for you, you have not been powerless, but your ego also indicates you have also not been humble.
Some might call that delusional and ignorant.
Ignorant because, if quitting was as easy as, saying it, people would not be dying like flies right now and there would not be world wide drug epidemic.
So somewhere between your ego and ignorance is something missing.
That thing missing is humility and what stands in its place is a haughty spirit and pride.
Maybe one day I, me and my may require to become we.
Then you will know what powerlessness is, and humility.
