I find NAC better than anything. It is a natural compound that shifts mucus. It is used in the treatment of Cystic Fibrosis. 600mg 3 times a day. It is safe to take with everything except blood thinning drugs. H&B sell it as do many online retailers.
Yes I usually let things take their course but I’m fed up with this cough. I’ll guve NAC a try . Going to H and B today so I’ll get some there. Like you Sarah65 , once I start I can’t stop. Embarrassing!
