I love how you took this challenge on as a personal survival issue. Too cool!

My advice (to echo MDinana and a few others) is:
1.Take your meds. Don't view them as a "failure" to have to take them. They save lives. They are primarily to prevent a heart attack, which can happen even if you are exercising, etc. You are now in a very high risk population for cardiovascular events.
2.Keep losing weight. Weight resistance exercise anternating with aerobic 3x week appears to be ideal.
3.If you choose to take supplements, do your homework and use ones that have some decent peer-reviewed studies behind them. The chromium picolinate has some promise, but there is conflicting evidence that it may damage DNA. Alpha lipoic acid (ALA) however, is an excellent supplement and you consider taking it.
4. Don't give up on finding that diabetes educator. They exist in many outpatient clinics. It will open your mind to possibilities and especially eating patterns and help you counter the diabetes myths that are out there.
5. Lantus insulin is great, but having to go on the more immediate releasing insulins can increase your weight, which can increase the need for insulin, and it's a vicious cycle. If you can keep your A1C's good with just the oral agents, be happy!
6. The statin and ace inhibitor are just as important to your health as the other agents you should be taking (I'm guessing they started you on metformin). Oh, and the aspirin!
7.Proper fitting shoes and checking your feet is critical if you have any foot neuropathy, but hopefully this is not in your cards.
8.PMA!

Best of luck!
