Ryan, I think your question is a little difficult to understand as others mentioned. Correction doses are actually a good thing (when done properly) and the point of administering them is to avoid hyperglycemia (high blood sugar).
The goal in all of this is to maintain "Normal" blood sugar levels and avoid hyperglycemia and hypoglycemia. Of course, that's easier said than done and there are plenty of people who have lived with diabetes for decades who still deal with the "Rollercoaster."
As someone who was diagnosed about a year ago, my general approach is to give myself a correction dose, give that insulin time to be absorbed, test 20-30 minutes later, and repeat as necessary. I know how frustrating it can be to give yourself too big of a correction dose and then find yourself sucking down sugar shortly after.
Personally, I'd much rather brave giving myself multiple smaller injections to correct a high than to try to fix it all in one single injection. The same is true in the opposite situation (hypoglycemia). I usually eat one or two glucose tablets (4g or 8g, respectively), test ~20 minutes later, and repeat as necessary.
