Clients usually know when they have mastered and ameliorated their traumatic memories. Again, this should be a collaborative decision, made after exploring the reasons for the failure. Obviously, it is best to suggest that the method failed, not the client. The question of whether and when to schedule further Counting Method sessions can be delayed until a later time. The first session usually leaves the client with more than enough to digest.
Some traumatic memories are relatively short and specific.
These require relatively few sessions. Some are varied, multidimensional, with multiple meanings for the client. For example, a woman who was raped recently and abused as a child may require sessions dealing with several discrete episodes. She may prefer to have these spaced months apart. A person held hostage for days may have many elements of a prolonged trauma that he or she wishes to remember during a half dozen counting sessions.
