Awesome job noting the routine and how it ended up triggering hunger feelings when you weren't really hungry =)
This is just another reason why habits can be hard to break. Using the TV as an example... if we're used to snacking when the TV is on, breaking that habit is hard... we're changing our whole routine!
But, it can work the other way, too. It can help us stick to a healthier routine. Like having a bedtime routine for a child. Brush your teeth, take a bath and then it's a story and tuck-in-time. It signals to us that it's bedtime and we start getting sleepy.
In adults we have to force the changes at first, but over time the good habits become easier as they become routine.
I wake up, bathroom, then it's time for water and a workout. Even after two months... I'm finding I have to think about it less and less. It just is what happens after I wake up.
So... long-windedness aside...it can work for and against us! So it's awesome you're taking conscious control!
