i would love to throw in some suggestions for you. I have been type 1 for 41 years now, so hopefully some of my trial and error discoveries can help other folks. For me, the real key to good control is just focusing on what I need to do to achieve good control within the next 3 hours. Meaning, I don't even look at the future beyond correcting what my levels are right now. Each time you do a correction, you take care of yourself for the next few hours. Now, for me, the key is testing often and adjusting often. When I do this, my a1c drops. When I don't test and adjust as often, it rises.
So the next issue is cost of supplies. I totally understand. The new health care laws will not help a great deal with costs, for co-pays go up and up each time the industry evaluates. But maybe there are some suggestions to help you. One is, are you living in a region of the country that has HEB grocery chain stores? If so, I recently discovered that they offer a generic HEB brand needle-syringe unit in both the normal sized needles and in my personal favorite, the tiny 31-gauge 5/16" needle. Much cheaper than the BD brand syringes that I have always used because there were no other options. This was an amazing discovery for me.
Furthermore, there are other ways to get cheaper supplies, and the Juvenile Diabetes Research Foundation (JDRF) has a staff member who keeps on top of ways to help people who are uninsured or under-insured. I suggest that you go to the wwwjdrf.org website and click on the link to the Online Diabetes Support Team (ODST). Send 'em a message stating that you are seeking help with the cost of supplies because your insurance company's coverage is inadequate. They will send you to this gentleman, who may have some options for you. He keeps lists of aid available in various states. You have nothing to lose and may be able to get some help this way. I believe that some of the glucose monitor companies even offer aid with test strips, etc.
Last but not least, some brands of insulin are cheaper than others. I suggest that you call your insurance company and ask if switching brands may help you. I just found out that Blue Cross Blue Shield prefers to have people use the less expensive Levemir long-lasting insulin rather than Lantus Glargine insulin -- co-pay is less. Obviously, you would need to find out if switching brands would help and would need to work with your doctor to do this. It may or may not work for you well.
For women, part of glucose control is hormones. Some women find it impossible to achieve good control during certain times of the month because of high levels of hormones that work as insulin-blocking agents. So we become insulin-resistant at certain times of the month. I have never heard a doctor address this issue, but it can be a huge factor for some women while others don't notice as much difficulty. I suggest that you perhaps keep some sort of record of WHEN you find that your levels are high for days. Often, this is at the end of the monthly cycle, followed by a drop in glucose levels when those hormones drop and your body starts responding normally to insulin again. For me, finding this out and then watching the timing helped me achieve better control than in my youth when I did not know this link between hormones and insulin sensitivity. If you are one for whom this is a big issue, then eating a lower-carb diet on those days may help lower the high levels while you wait for hormones to equalize.
