I'm just emerging from 2 more days in bed with a wretched cough after i thought it was getting better but it returned again on Wednesday. Currently on teaspoons of local runny honey to help. A natural expectorant with other properties and some nutritional value i guess.
Reading your post though Autumnwalks it puts things in perspective. Take best care of yourself. X
