I have 2 of those Mango, if you have the vasovega SP? clenching your toes (like making a fist but with your toes) really helps, and a little trick I learned was to put a little vapor-rub under my nose right before its very soothing and helps calm me. I passed out once in the waiting room before getting a shot while sitting in a chair, just the thought of it. As I have gotten older I have been able to control it much better with little tricks just to help refocus my brain (anxiety) - but I don't know if it works on the other ones.
