Last week, in frustration that I still didn't feel wholly recovered from all the work-related stress from last year I decided to look at what might still be wrong from a biochemical point of view. I took as my point of departure that I have incessantly been craving a certain mundane food item for months on end. On the assumption that cravings are the body's way of notifying you of a shortage, I reseached the nutritional value of said mundane food item. Above all one mineral stood out. I researched the symptoms of a deficiency in this particular mineral and found a perfect laundry list of the what's been ailing me. Everything from the depression and anxiety to skin problems that I hadn't even considered as possibly related.
I seemed to be on to something so I picked up some pills to suppliment my diet (and to keep the particular deficiency in isolation - if they didn't work then I could explore other aspects of the food I was craving). It's been a week now and I am feeling remarkably better. I wish I had put two and two together ages ago, my only excuse being one of the effects of the deficiency I seem to have hit on is a lack of mental acuity.
