I have suffered from chronic Depression for years now, since I was about 20 (I'm 27 now). I also have bad sinus problems, only ever breathing through one clear nostril at any one time. It recently entered my mind that my sinus problem (that I have had all my life) may be part of the reason for the depression. Your post interested me as its the first time I've seen someone mention a sinus problem in relation to depression. I would like to know what product you were referring to in your original post in the line "Then after much resarch I decided to go on the MC, and take B&P, for ten days".
I have also recently begun colon & Liver Cleansing using Dr Schulze' preparations and I hope that this will help me.
