Placebo by stress and concentration

Hello everyone,

We are working on an inquiry about the use of placebo for reduction of stress and for improvement from the ability to concentrate. We have some questions about the use. Maybe there are some of you, who can answer the questions or a few of them.
-Do you have any experience with the use of placebo and how was this experience?
-If you have used both placebo and regular medication, do you experience a difference between the two?
-Was reducing stress and improving concentration sufficient and were you able to function as required?
-At what time did you decide to switch to placebo instead of the regular medication. Did your doctor play a role in this?

Thanks in advance for your comment.

With best regards,
Akkie Bouwmeester and Celeste Tellegen.
