Yesterday wasn't too bad of a day. I stupidly drank a 20 oz. glass of Sprite in the afternoon. I could feel it immediately going to my head but I drank it anyway. This morning I awoke with the pounding head and neck pain. There is no doubt in my mind that it was the Sprite! My head has hurt all day and is just barely starting to ease up some. (It is now 5:50 p.m.) I am about to take my second dose of the Glutathione combination. There is a seminar on Monday that I am going to go to to learn more about this product and why it is patented. I am sure that I will not have a headache in the morning because I have been very good about my diet today. It is amazing how what we eat can take us down so quickly!
