Without having read the info suggested above, I have a couple of suggestions:
(1) If you are taking medications for other conditions, such as high blood pressure and/or cholesterol, research the side effects in those medications for the possibility that they are causing the high sugar numbers. Discuss changing the meds with your doctor to see if the sugar numbers decrease.
(2) Before going on insulin in any form, register with a diabetes education program. Many hospitals and HMO's offer these programs free of charge. They show you how to regulate your diet, increase your physical activity, and test your blood sugar. Your primary doctor should have testing kits at no charge.
Many medications come with warnings that liver or kidney damage may occur. The logical question is: can they also cause damage to the pancreas? When the pancreas doesn't function properly, the liver steps in to back it up. (I think I read that somewhere.) If both the liver and the pancreas are damaged, the body is not getting or cannot use the insulin these organs may be producing. Doctors should be monitoring their patients on certain meds on a regular basis to prevent the onset of diabetes. The incidence of adult-onset diabetes is growing higher every year. Is anybody questioning why?
I am regulating my blood sugar as recommended in the diabetes class operated by Kaiser Permanente without medication. (I understand that most insulin meds work for 2 or 3 years at best and then have to be changed or supplemented with a second med.) There is also some debate as to whether insulin causes weight gain -- the opposite of what a diabetic should experience. My doctor told me the med she wanted to start me with would give me "the poots" and make me hungry all the time. Could she hear herself talking??!! What she didn't reveal was that this med has been known to cause heart attacks. I am already a heart patient. Thanks for nothing.
I agree with the other posters that you should get educated to understand what is happening to your body and how you can minimize the damage. Ask questions, do your own research and make your doctor talk to you.
It's interesting that you kept it a secret as to how you came to the conclusion that "I have high blood sugus reading" when, in your words, "never done this before". How sure are you that your readings [glucose test results] were accurate, not a false positive? As suggested by the prior poster, first read the information on Medhelp diabetes, or Google "diabetes", then go see a doctor for correct testing and care instructions.
