The short answer is yes, you can trade one addiction for another and no, it doesn’t necessarily cause spiraling.
The long answer is yes, with a great deal of patience, you can condition yourself into just about anything. Breaking from an addictive personality is far from easy and requires a deep understanding of yourself and your triggers. Introspection and therapy aplenty. There can be relapses or worse if you try to hack together a treatment plan for yourself. Support groups can be helpful and leaning on friends and family, when possible, can make or break you.
