I've been struggling with hunger pangs this week and unfortunately, giving in.
BUT, I do consider it a victory, as you do, not to be indulging in the same stuff we used to, or at least the same amounts (which were just sick for me).
When it comes to hunger, I usually find the feeling passes. The less I ate at night, the less hungry and more able to deal with the tinges I did have I became. Tea was a big help. Cup of herbal tea and surfing around 3FCs pretty much constantly.
I know some of the ladies have recommended saving calories for a later snack.
For the most part, it's the old advice -- drink some water, find ANYTHING to do, and wait it out. If you're still hungry, make a better choice and move on.
Congrats on making it to day 4.
