Hi B.,
I am sorry that I don't know anything about the light circle that you talked about, but the sweating sounds just like my son. When he was little he used to sweat profusely when he went outside and it did not have to be hot. He would sweat on any exercise and when he was asleep as well his head would be wet. We took him off all dairy products for other health reasons and with 3 days the sweats had gone. It was really amazing.
Hope this helps. THere are a lot of other alternatives to milk so even if you try it for a week you may see a great change.
Kind regards,
W.
