If I eat a candy, do I have to make a bracha achrona afterwards?

If I eat a candy, do I make a Bracha  Achrona afterwards? The answer is you do,   if you eat enough. It depends how much you eat  and how fast you eat it. If you eat a Kizayit,   which is about the size of half an egg, and  you eat it within three to four minutes,   then you would make a Bracha Achrona, usually if  it’s candy it’s probably a Borei Befashot at the   end. But oftentimes, a person  does not eat it fast enough,   they might eat one sucking candy in three to  four minutes, in which case you do not make a   Bracha Achrona. So a person might be eating many  candies, much more than a Kizayit over a span of   time. Unless it was this span of time, you have to  have three to four, some say even slightly more,   it could be up to nine minutes according  to some opinions, But if you didn't eat   a Kizayit of candy within that amount of time,  then you do not say Bracha Achrona at the end.
