This chemists is only small but it has one massive advantage over all others. It sells its own cough remedy which, taken with warm water, tastes quite vile but is guaranteed to give almost instant relief. My mum was really ill with a cold and a cough which had kept her awake most of the night for 3 nights running. She was so exhausted that she was like a limp rag. Someone told me about this magic linctus and I bought a bottle. After taking it she had her first full night’s sleep in ages and was soon on the mend.
