Welcome thisibelieve! You found a great place for support & friendship.
I was very tired for a few weeks after quitting. It takes a while to heal from all we've put ourselves through. I agree with lala - keep it simple. Tiny baby steps at first. I also had the sugar craving & it finally settled down too. I mean, I was grabbing lollipops - anything - to pacify myself. The only remaining obsession is ice cream.
I'm happy you joined us. I hope you'll find the help & encouragement you need.
