I'm on day 15 of a sugar-free challenge ....and it's hard! I felt so angry and cranky several times. It has really taken alot to stay on plan and to be focused. I hate actually spend the first few days eating lots of dates to help control my cravings. I grew up eating sugar every single day so it's like an emotional bond, physical craving, and habit that I'm dealing with all at once.
After time though you will feel radiant.
