Hi Gini.
Yes, the calm euphoria was very evident because it was such a contrast to my mental state before!
Also what I noticed, as well, was that setting 3 was sooooo different than setting 2. Setting 2 did not give me euphoria or a feeling thought clearing.. I just felt kind of a dopey sleepy feeling.
All the best.. I hope you can find a way to get it to work for you..
