I must confess I have quite a few slip ups and bad habits. Especially things related to what you said. One habit (which I'm stopping) is eating junk I know I shouldn't and try to compensate with extra insulin (T-1 here).
In the end, my body tells me its just not worth it. Then its really just a matter for me to change those habits/my lifestyle. I guess you can only wake up feeling like **** (or feeling like **** in general) for so long
