I think it makes sense to actively suppress, to make a conscious choice to not indulge hedonistic whims or yearnings. Is that dissociation?
The RR idea is to separate from the urge to drink or use by saying it comes from part of me that really oughta shutup because it is going to kill me. The hedonism part is ok, it is merely our nature to seek pleasure and avoid pain, and there are very good evolutionary reasons for us to feel this way. Sometimes, though, this pleasure seeking goes awry and leads us to addiction to a substance to which we develop an increasing tolerance. We start making bad decisions and keep doing it, even to our detriment.
At least I did, anyway.
