One of the first actions we take at Passages is to ruthlessly scrutinize, always under a doctor's supervision and care, the specific necessity of any mind- altering or mood-altering medications that our clients are taking. As soon as any non essential drugs are out of their systems, the feelings they were trying to suppress usually emerge. When that happens, we can see what symptoms the client was masking with drugs or alcohol.
