Sugar and caffeine cravings with ADHD?

My grandson always wants Mountain Dew and candy, is it just him or do all of the ADHD children 'crave' these jolts? We all know what happens when they get them, especially that soft drink!

My 15 year old son is the same way. With him it’s not as much a craving but the fact he knows he shouldn’t have it. We all want what we can’t have. When he has these things in moderation he does ok. Something we have found to counteract too much sugar is a glass of milk. Sounds strange but it works. My son gets silly and unfocused from too much sugar and the milk seems to calm this down a bit.
