you can still have snacks, you're allowed 300 cals a day of snacks, maybe plan some for after dinner.
I tend to have my snacks between my meals during the day. I'll look at breaking them up a bit more. Most of the time I can cope at night. It is when I am bored or from habit. I have to say my ironing is up to date as I used that as a distraction not to eat!

It's normal to feel hungry for the first 2-3 weeks, expect to.once your metabolism starts working more efficiently and your vlood sugar levels are a bit more balanced you won't feels as hungry.
If you want to a chromium supplement (a few brands make them, blackmores have one) can help.
What does chromium do?
