One after-effect I've noticed since the experiment was that I am much more relaxed, centered, and focused, with an over-all "good" feeling throughout my entire body. This persisted even up to when I went to bed and woke up the next morning.

I think this is a benefit from the "Comprehensive Intervention Procedure" and the "Finger Interlock" technique that I did before the HDR experiment yesterday. If anyone reading this blog trys these techniques out, post your experiences in the comments section here. I will try the HDR experiment again today, with some minor changes.
