No, I don't do any of those.

I just... forget to eat. I get up in the morning and make a cup of coffee or tea. I get the kid off to school, get myself ready for work, catch the train - then realize I didn't have any breakfast because
I wasn't hungry or food wasn't appealing.
More of the same at work. If I didn't eat breakfast or lunch, I'm usually ready for a snack about 3pm. If I eat too much then - I'm not hungry for dinner. And hungry for dinner or not - it's hard for me to consume adequate and varied nutrition between 3pm and 8pm.
Not every day is like this. Sometimes, I have apparently-normal hunger cues - and if I skip breakfast, I'll eat a bigger lunch/dinner/snack to compensate or I'll unconsciously alternate a low calorie day and a high calorie day. Then I relax, and eventually not-eating sneaks up on me again.
I tried a cell phone alarm, and it sort of didn't take. I might give it another try, but most of the issue is that I currently suck at eating when I'm not hungry. I need to remember all the ways to eat without thinking about it. Tomorrow I'll try chai or Cafe au lait instead of black coffee/plain green tea.
