Guys,I have been a medic for a long time and I can not stress how dangerous this stuff is. I can think of two instances off the top of my head that would hopefully change your mind about messing around with your insulin levels. One was a body builder shooting insulin, probably in what he thought was a safe manner. The other was a pill head that stole a family members meds. He thought he was taking a narcotic but what he took was Glucophage. Remember, your brain uses something like 30 to 40 % of your blood glucose. And when you take these Meds you run the risk of depleting your levels very quickly. Even with rapid treatment and medications designed to increase their blood sugar,the meds these guys took worked too well and they are both vegetables now. Both very young and both with zero chance of improvement.
