Need Diet advice

I am a diabetic, have been for six years.Up until about 2 years ago I have been controled with diet only. For the past two years I have been taking meds and fighting my blood sugar. I started on glucophage, worked well for a while then my sugar started climbing up. SO we added Beata (Spelling). I was only on that for a while because I had some problems but think I may want to try it again. After that I was on Glocavance but that bottomed out my blood sugar.

What I really need is advice on dieting because I am obviously not doing that well. I have tried every diet known to man. I have never been able to keep weight off. I also need and exercise plan that I can work with. What works for you? Maybe it can help me.

Thank you
