Hi Bel and welcome to the forum!
Kicking the junk habit is hard. It takes a few months to get into a new healthy habit, but once it happens it's soooo much easier. Nowadays when i slip up it's usually over 1 or 2 biscuits rather than 1 0r 2 packets of biscuits which makes a huge difference.
Try switching slowly to healthier options. I found instead of adding sugar to my breakfast (or eating sugary cereals), say, I would put on fruit like stewed apples or sultanas. If you NEED lollies or chocolate try carrying a little bag of dried fruit - dates are a fantastic chocolate substitute, or try switching to a higher cocoa chocolate (I have Lindt 85% cocoa - you can't eat it all in one sitting and it's healthier)
The trick is to do it slowly though, otherwise it's too much to change at once and you might get overwhelmed.
Good luck with it and I hope to see you in the forum!
