Has anyone heard of CVAC Systems or had the opportunity to use it? CVAC stands for "Cyclic Variations in Altitude Conditioning". Also from their website - "CVAC Systems, Inc.’s primary focus is researching the potential of the CVAC process in insulin resistance, metabolic syndrome and diabetes." I ask because my sister saw a doc yesterday who mentioned it to her. She does not have diabetes but it's used for performance enhancement as well - evidently the doc does it who is an avid runner. Needless to say he said they were doing a study at UCSD on those with type1 and type 2 diabetes. I'm curious if any of you San Diego folks have heard about it. I do not see it listed as a study on their website. Not a cure but maybe it can help until one comes along. Here's a link if any of you want to take a look. http://www.cvacsystems.com/corporate.html They are based out of Temecula, CA.
