My 6 year old son has had the same reaction to McDonald's Soft Serve Cone as posted on your website. It started about 20 minutes after eating and lasted about an hour.  It was not the thing to have before a swimming lesson. He was behaving as the mother noted on your website (Story [850] – “our normally quiet son bounces, jumps, shouts, makes silly loud noises, blows raspberries, uses nonsense words, and generally just can't sit still”) and appeared to be on a planet of his own! – Trina, NSW
