Pooh, better not to try medicine from gp. Co's my previous pregnancy, I showed my gynae the medicines my gp gave, 3 out of 4 med he rejected. I am also down with cold and dry throat, I just use warm water salt solution to gargle. Try to drink more warmer water, no orange, chicken, cold water, it makes coughing worst. Take care.It is normal we get sick easier Co's our body protecting our Beanie, So less resistant to sickness.
