Rich,
I have had diabetes just a little longer than you (27 years) and can relate to what you have written. Its good that you have overcome the first obstacle and admitted that you need to tighten things up a little, that's the hardest part sometimes!
Notice that your hba1c is rather high at 8.5-10. Sometimes a small adjustment is all it takes to improve these figures. I don't know if you know how to carb count correctly and match your insulin accordingly, have you attended a course to learn these skills? Should the answer be no, perhaps it may be worth your while asking your diabetes clinic about DAFNE courses in your area. The DAFNE course teaches patients the principles of matching insulin to the food you eat, often with big improvements in hba1c's.
A reduction in the carbs you eat could be something else to consider. Many of us on the forum have reduced our carb intake to levels which have given us stable control together with improved bg readings. Read through the forum and look at diet advice, low/reduced carbs, low-gi/gl diet etc.
I use the reduced carb and low-gi/gl approach with great results, this means that you can still enjoy most of the foods you eat now, except that you are eating reduced quantities and foods that are kinder to your blood glucose overall.
Should you have any queries, do feel free to fire away or you can pm should you prefer.
