I agree with this! My partner is diabetic, and occasionally if she miscalculates her insulin, her blood sugar crashes and I have to sort her out, needing lots of sugar quickly.
Irn Bru or Coca Cola is usually her preferred method, but these days it can take up to three cans to get her back down to planet Earth, which has other unwanted side effects. A return of the full sugar variety would be very welcome!
One I miss is a pub snack called Cheese Moments, sold from cards like scampi fries and bacon fries are, so presumably the same makers. They contained a sort of semi liquid cheese which I think had never seen a cow, but they were strangely moreish if probably very unhealthy.
