Before I started taking vitamin D, I was almost a recluse in the fact that I didn't want to meet people incase I caught a cold. I have very good reason having lung disease it makes me very ill when I catch a cold. Just a few days into starting the Vit D I had to take my dog to the vets and when the vet called me in it was very apparent that he had a streaming cold. He knows me and so he knew that I was scared of his cold so we had this strange conversation with him on one side of the room speaking to me with his head to one side so his breath wasn't coming in my direction and me on the other side looking away from him!! When he came closer to examine the dog I moved away and it was quite comical, however, I told him that I hoped that this wouldn't happen any more and we got talking about Vitamin D and it turns out that his small son is asthmatic and of course gets very sick when he gets a cold and so he was VERY interested in what I had to say as I think he said he was sleeping in the shed while he had the cold!. I was also interested to know if animals needed extra Vitamin D as well and he said he would look into it. Thankfully, I didn't get the cold and the vitamin D message is going down another route now!
