I stopped taking Metformin several months ago and weaned myself off the Blood pressure meds. They made me feel like I was going to die at any moment. Since that time I went through the roller coaster ride with the Blood Sugar too. The first nutrients I bought was Vanadium, gymnema and bitter melon. My personal opinion on bitter melon is that it is a miracle food for diabetics. Capsules were cost prohibitive so I purchased a pound from a seller on ebay. It was the 3rd pound I had purchased from several sources, and found it of good quality. It takes some getting used to as it is bitter but I kind of like it now as a tea or additive in my foods. I use one heaping teaspoon 3 times a day. Since stopping the Metformin it has been a slow spiral down toward normal. My blood pressure is lower without the toxic poisons too. I must say though I have not felt so good since I was 40. I am 64.
