Short answer -- YES -- It's a constant juggling act.
Long answer -- You may be sorry you said I wasn't boring you. You probably know a lot of this stuff already.
The body runs on glucose. The body converts all the carbohydrates (and only the carbs) we eat into glucose. Since we don't eat little tiny bits 24/7; the body produces insulin to assist in keeping the amount of glucose circulating in the blood at an even level all the time. What insulin actually does is control the flow of the glucose into the cells. It unlocks the cell door so to speak. It has two jobs, actually -- it unlocks the door on the muscle cells for the glucose to get in and it also unlocks the door on the fat cells for the storage of excess energy that we don't need to put into the muscle cells immediately. Excess carbs, excess fats, and excess protein can all be converted to fat if storage is needed. The average body does a wonderful job of keeping everything in balance.
HOWEVER . . .
In Type I Diabetes due to an unknown cause, the Islets of Langerhans (the area in the Pancreas where Insulin is made) just suddenly stop functioning altogether. A Type I must inject Insulin to live, and it is a constant balancing act to enusre that the right amount is injected. Too little insulin and you die.
In Type II Diabetes, the muscle cells become more and more resistent to the Insulin being produced. Again, the cause is unknown, but obesity has a lot to do with this problem. The Pancreas now works even harder to produce more and more insulin in an attempt to keep the body functioning. Now the catch-22 to all this is that the fat cells do not tend to become as resistant as the muscle cells. The increase in production of insulin means that the fat cells get more and more stuffed into them and that in turn seems to make the muscle cells even more resistant.
And so the vicious circle continues. The Type II diabetic needs more and more medication to help the pancreas creat more insulin and the body to use it better until the pancreas cannot cope any longer even at maximum production and then the Type II has to start injecting additional insulin making weight control even more difficult.Deep breath . . . against all odds (and with a lot fewer calories than needed for non-diabetics) the Type II finally manages to lose some weight. So, suddenly there is too much insulin and the blood glucose level falls too low. Too much insulin for too long and you may die because the heart and brain will shut down from lack of glucose. Constant juggling is required to keep things in balance. I guess the faster the weight loss, the more juggling but weight loss is so difficult, speed is not usually a problem for a diabetic.

Bottom line -- is it worth it -- absolutely. I'd rather be constantly juggling my insulin and meds than constantly having to take more and more.
Getting contol of diabetes with the fewest medications possible helps to reduce the risk of all those serious complications. Did you know that Diabetes is by far the major risk factor for death by heart attack? And, the single biggest cause of blindness and non-trauma induced amputations. All the extra glucose in the blood does devasting damage. It is definitely worth all the hassles.
Okay . . . I'll shut up now . . . thanks for listening. Hope you are still awake. Have a great evening . . .



. Or maybe it is exactly how much we feel like doing right at the moment.
Seems like my latest insulin idea (a morning shot yesterday but none at bedtime) worked out fairly well, so I'll do the same again today and see where things go. Just had a nice breakfast of HF cereal with mixed berries and skim milk.
. . . by Wednesday, when it does? -- only the scale
knows what he may feel like by then. 
At least it's light (in weight) so the ED is a mere 1.7 (for Fat Free), 2.2 (for Light), 2.9 (for regular). 
weather right about now.
