New to diabetes control

I was diagnosed with diabetes several years ago, and place on regular doses of Avandia. We retired in Mexico and my B/S was relatively in control. After a year, I ran across the news about the dangers of Avandia. I quit taking it, immediately, figuring I could find an alternative. However, I continued to test my B/S on a daily basis. I was very surprised to note the numbers were very low to normal, without the medication (generally between 90 and 120) and maintained that level consistently. It got to a point I didn't feel regular testing was necessary. I would still check it once or twice a month, but it stayed at the same level. Eventually, I quit testing it all together. I was getting lots of exercise, though I was still over-weight, and eating fresher foods. We lived in Mexico for 5 years. Now, we have returned to the US and live in Auburn, CA. I got away from the exercise and, of course, our diet changed as well. Now my B/S is totally out of control. I got on VA Health Care and my doctor put me on METFORMIN HCL 500MG TABLET twice a day. I was told to take a reading 3-4 times a week. It's been averaging 195.

I did start a walking regiment, covering 1-2 miles a day, but I fell a month ago and injured my knee. I'm still able to walk, with little pain, but when I stop, it starts hurting. Therefore, I've been back-sliding on it. I've tried some aerobic exercises, but I'm having a real problem getting myself motivated to do it consistently.

There's my story, and I'm stickin' to it. Any feedback or suggestions would be greatly appreciated.
