Why does client’s husband [name withheld] still have bad breath after his clearing? What is it from and what do we do now?

Her husband’s breath is an indicator of inner discord. This was not produced by a negative spirit, as you presumed, especially with its resolution following your Remote Spirit Releasement work done on him previously with your Protocol. This is actually a karmic issue that was being stirred up by the inner presence of spirit attachments and so this symptom appeared. It was indirectly associated with the spirit presence but was not caused by them as a side effect directly. At the present time, he has been free of spirits once again, but the karmic issue was stirred up and this has not yet been fully healed. So another application of the Protocol is in order to do follow-up work. This is something he is unaware of consciously, so it will be difficult to approach with subconscious channeling and the HMR work, as you may well get other issues, and not this one in particular. That is why a more generalized approach with the inclusion of this phenomenon as a client issue, is the best way to continue to work on this.
