Why has my client with chronic cough not improved following the two sessions of Deep Subconscious Channeling with Trauma Resolution? Is the cough actually due to taking Metformin, as she speculates, which is a reported side effect?

Here the cause is truly karmic, not pharmacological, and again the issue of responsiveness to the work is one of more time being needed. An additional session would speed things as well. After all, what you are needing to happen here is to reach a tipping point, not necessarily a total resolution through a rebalancing of every negative experience coming to bear on the genesis of the problem. The more that is healed, the better, from the standpoint of clearing karmic baggage. But, in a practical sense, reaching a state of becoming asymptomatic is an important goal in its own right and is deserved. We see this coming to pass one way or the other, whether it is accelerated through additional work or not, so we leave this to your discretion.
