I'm also experiencing a more even temperament generally. The same problems are there, but the amplitude is reduced, as are the swings. In simpler terms: I'm still upset about a lot of things and have some pessimistic opinions, but I'm no longer staring at the wall thinking about them for 9 hours straight.
I'm also sleeping between 12 and 14 hours a night, which is both therapeutically deemed to be "good" and pleasurable.
So far my rating for neurofeedback as a therapy is a conditional positive. I've got improvements that are good and important, but getting there was disagreeable in the extreme.
