I quite liked Caramac, though I won't miss it.
But the sweets they should get rid of are:
Parma violets - taste of soap
Maltesers - teachers get loads of these and I know for a fact they all hate them, though even they are not as bad as those disgusting "Thank You" chocolate flowers that Cadbury's put out a few years ago
Cadbury's creme eggs - just thinking about them makes my teeth hurt
But most of all, most of all, those horrible gelatine things in Licorice Allsorts covered in little blue and pink balls that are always the last ones left in the bag. You want to throw them away but always end up eating them even though they're nasty and will leave a disgusting taste in your mouth for ages afterwards.
