Too much snacking, too much delay between meals

Now that work pressure has stepped up, regularity of meals is taking a hit and irregular snacking is turning up. Trying to balance it as best I can but occasionally there is that 5 hour distance between breakfast and lunch. Not acceptable. Eat small meals every three hours. Stress also seems to be adding to the need to snack in between meals with irregularity. Including on carbs at night, while having green tea. Milk or yoghurt disappearing as a nice night snack, being substituted by soup sticks and the like. Must check this tendency. And not the least, having dinner too late at night, not enough distance between dinner and bedtime. Must check! Each meal getting delayed by an hour or 90 minutes, not on. Small, frequent meals. Small portions. Low, measured snacking.
