Query: Best product ever for sinus and throat problems

We loved these Airborne Gummi Lozengers, which worked better than anything we've ever found for stopping in their tracks respiratory problems such as colds and allergies. They were easy to pack and carry with us, never requiring water. After having relied on these for many years, they are no longer carried. It's such a shame.
