I have tried sessions with energy/lightworkers, but not for extended periods, so I can't give an account of long-term effects. I know that I did feel a little better after a reiki session. It was really subtle. I was driving home and trying to figure out whether or not it did anything, as I couldn't feel any change in my mood. But then I realized when I stopped for some food that the "cloud" that was in the back of my mind, but not in the forefront mood, had lifted. This lasted for a few days, at least. A similar situation with a shamanic healing session some years back.
