Great Source for Catholic Therapists or Alike
Format: Paperback
This text brings about a new meaning of therapy in a profound way. It explains in-depth the dignity and wholeness of the person with a great potential of flourishing and healing.
Also, the text intertwines psychology, philosophy, and theology, which may seem contradictory at first glance, on the contrary, it is very much appropriate and, in a sense, enlightening.

Relief for dry mouth without gum irritation
Big improvement for users with sensitive gums. These relieve dry mouth during the night almost as well as the regular tabs. Some complained about a residual gel left on the gums. 🙄Just wipe it off. It’s a small thing.

This version doesn’t work
I used these 2 nights in a row. I was hoping Oracoat found a solution to the problem people like me have with the regular Xylimelts: irritation of gums. As others have noted the “sensitive” version doesn’t melt and the goo that remains can be difficult to remove. I didn’t have too much trouble after the first night. However, the second day after use, it was so hard to get the remains out, I wound up with a very sore spot from digging it out. I will toss the rest.
It’s too bad this effort fizzled. I hope Oracoat will find a solution For sensitive mouths. In the b meantime, I will use the original for a few nights and then stop before repeating. The idea behind the original product is fantastic. Unfortunately this attempt to make it usable for people with sensitive mouths hasn’t worked. Please try again.
