Which ones would you use? Are there sufficient ground for the use of countable noun usages for the words
"treatment" and "disucussion"? No explicit mentioning of the words seem to have occurred, yet two countable uses have been occurred, I think. Why?

treatment or treatments? Why?
1. I think we need to rely on the holistic approach to medical treatment and I think physical theraphy is an important part adjunct to drug treatments.

discussion or discussions? Why?
2. He entered the classroom and boldly argued for the benefits of physical theraphy. Daily he took students with him and held discussions with them.
