I have been researching how to get rid of this for a long time. There is a lot of information in a book called “Depression Free Naturally” by Joan Mathew Larsen. She has a Wellness Center in Minneapolis, MN. I know this does not totally answer your question but hopefully it might help you a bit. Also I found a doctor in Organ that will give you a free 15 min phone conversation. Her name is dr chapman. you can email me for it or you can google it. I tried to put in her website but it wont let me if you have found anything out about this can you please email me.
