I try to take my iodine three times a day, so I usually take 10 drops at a time, two or three times. If I am working away from home for the day, the "lunch" dose is difficult. On those days, I try to add 10 drops to my water bottle. Some days I forget. As Dolls has noted, we are organic and it is normal to ingest varying amounts of nutrition in a day from our foods, so it makes sense to be less than perfect about about our iodine. I listen to my body. It will tell you when to add and when to stop. With our food supply, I am not sure I will ever be able to stop.
On the snot and boogers note, my sinus issues come and go. Sometimes I notice a problem immediately after iodine; other times I don't - same amount of drops. I had a particularly "sinusy" episode a couple of days ago, but I think that was probably the Sangria and spicy appetizers!! Yum!
