I've treated all sorts of addictions in my practice, such as ones involving drugs, alcohol, sex, gambling, etc. And I observe that the process of change is often circular rather than linear. There is really a need for adequate time to pass with the right treatment and actions.
Stage 1: PRE-CONTEMPLATION (person hasn't identified behavior as addiction)
"I'm well and ok, I don't see it as a problem."
Stage 2: CONTEMPLATION (at least experiencing ambivalence)
"I wonder if I gamble too much or if I have the strength to stop it"
Stage 3: COMMITMENT AND ACTION (turning point at which person decides to change or quit
"I can't go on like this any more! I've to change."
Stage 4: MAINTENANCE (efforts to keep off "drug-of-choice")
"I avoid the bars. I think of the consequences on my family and my health if I drink again."
Stage 5: RELAPSE and RENEWAL (failing or giving up on change efforts ...relapse is an aspect of
change and rehabilitation)
"Here I go again. I've to get back on track, renew my commitment to change."
