Hmm, okay. I was considering trying it on its own, rather than while doing something else. I know I wasn't able to do autogenics exercises while trying to do something else before, and now I sort of can after having practiced, so I would expect it to go poorly to try to go the other direction for the first time while otherwise occupied.

After you mentioned this I realized I have all the parts on hand to make a DIY galvanic skin response sensor. I got the hardware set up, and now I'm working on getting the software set up in a nice way. Hopefully it will work out :-)
