If you believe you qualify for insulin use, you will need to exercise extreme caution. The use of this powerful hormone improperly can lead to death, and we're talking about death shortly after administration. We're not trying to scare you; we're simply stating the truth. Remember, the release of natural insulin is due to the presence of carbohydrates, and if you supplement with exogenous insulin yet do not provide enough carbohydrates to match you may slip into a diabetic coma and never wake. A mixture of slow and fast acting carbs with your insulin is usually best, but if you start to feel sleepy do not go to sleep, start pouring more carbs down your throat; grape juice, candy and any other fast acting carb will do the trick. You will generally need 100-150g of carbs per 5-10iu of insulin, and a few EFA's and a little protein isn't a bad idea either. Of course, some will need more carbohydrates; this is impossible to predict. At any rate, you will find Humulin-R is your best choice as it has a half-life of only about 5-6 hours, clears fast and anyone can walk right into the pharmacy and purchase all they want without a prescription.
