Mostly works, but..........
I use these at night for sleeping with a CPAP. I am a mouth breather, so my CPAP mask is a full face mask, thus there is constant airflow going into my mouth all night long. While these tablets do help with reducing dry mouth, they only last about 4-5 hrs before they fully dissolve - which does not get me through a full night of sleep. Using two tablets instead of one only gives me roughly one additional hour. If you wear a CPAP mask, you also need to be careful of exactly where you place the tablets, because it will be quite uncomfortable if you mask ends up pressing on the tablet. If the tablet does not adhere well upon initial placement, you pretty much need to fully dry the tablet before re-attempting placement. If the brown side is already wet when you place it against your gums, there is a much higher chance of it just sliding off, instead of sticking. Overall, while not completely eliminating the issue, they do at least reduce the dry mouth problem during sleep.

Stays put and dissolves slowly. Orange flavor is nice.
If you have to use something overnight for dry mouth definitely get these. I use one nightly with my mouth guard. The orange flavor is very nice and it dissolves slowly overnight. It's small enough to do the trick, but not be overpowering. It stays put. And it works. Definitely notice the improvement inside my mouth.

This is a seminal book on psychotherapy. A must have!
Format: Hardcover
In the age of virtual (dis)connection, concerning high rates of depression and anxiety, and the importance of self-reliance and individualism, this book comes as a lighthouse of hope and direction. Attachment Theory in Practice is a must-have for any therapist who is looking to deepen their work and bring desired transformation and change to their clients’ lives.
The book provides a beautiful overview of the current state of the mental health field and the need for focusing on emotion, attachment and connection in psychotherapy. Dr. Johnson reminds us that “in order to shape optimal regulation that allows clients to harness their emotions for growth and aliveness, therapists have to ensure that clients are actively engaged with an emotional reality.” She echoes the findings from research on emotion regulation and suggests that “coregulation, rather than solo self-regulation, is the baseline, normal, and most-efficient strategy for us as social animals.” Dr. Jonson clearly posits that change is an emotional and an interpersonal phenomenon.
The book also outlines very practical guidance to working with couples, individuals, and families using the the attachment framework and EFT. As a therapist who is interested in science and empiricism, I am delighted to see the tremendous amount of research support EFT for couples has received over the past decade and I look forward to learning more about the findings in the areas of EFIT and EFFT.

A Foundational Book in EFT
Format: Hardcover
In a field of books about EFT, Sue Johnson’s new book provides an up-to-date summary of the latest developments in the EFT method, including applications for individual, couple and family therapy. Having been a student of EFT for 12 years or more, this book was more than a repetition of the fundamentals of the method, its stages and steps, which appear in her earlier books and have been elaborated by other authors. Here, I found her efforts to situate EFT conceptually in the field of psychotherapy, not only its attitude toward defining health and distress, but the underlying principles for its attitude toward how change occurs and its unique principles for how therapists help clients (individual, couple or family) foster change in themselves and their lives. She explains and illustrates the use of the EFT Tango moves, which implement the EFT method within the clinical dialogue and actualize the change process. No doubt, this book will become a primary source for future EFT training and is worth both reading and mastering cover-to-cover.

Broadens EFT Couple frame to individual and family work
Format: Hardcover, Format: Hardcover
I am really digging in to this. Even though it is an academic book, I find it highly readable and pragmatic. I am chewing slowly on pieces and am using my attachment TANGO (read the book) with my individual clients to great effect. Previously I would use an attachment frame but it wasn’t as focused and organized. Really an orienting perspective. Of course I am also integrating this precisely written guide with my couples, as I am an EFT couple therapist. And for classroom teaching the first few chapters alone highlight—and back up with research the reliability of attachment as a unifying frame. I call it my “map for human” and it
Really is. Thank you Sur for putting all that research in one place.
