Office/Corporate workers -how do you eat while at work?

LADS AND LADIES,

So I know with our condition and what not - were supposed to eat every 2-3 hours, 4 if youre feeling freaky. With that said - how is your eating schedule at work? I like to eat breakfast at 9, lunch at 12 - then I have this huge gap where I don't eat until 6. This is partially because I have a set diet that I like to follow. Should I be eating something around 3? I am asking this not because I get hungry or what not, but I am just trying to perfect my numbers as much as I can.

Long story short, after eating lunch at 12, should I be eating/taking insulin around the 3 oclock hour before I eat dinner around 6?
