It takes years for the damage to show in some cases, but the day your diabetes starts is the day it starts doing some harm in the body. Chances are you will get some complications in the future, but it can be sooner or later, depending how you take care of yourself. Do your best to take shots and test. Also know you will feel better with normal bg's.
