The length of application will depend on your results. I always run programs even after feeling the issue is resolved as a safeguard to a reoccurrence. As far as the "tingling" as your body improves you may not feel that as much or some never do. When I first started Spooky2 I felt tingling daily and now it is rather rare. That is a good thing. My husband has never felt any and yet we see improvement.
