Drinking 1 to 2 litres of water first thing in the morning has been talked about for a long time. So I thought of giving that a try about 15 days back. Now for the last 3 days I have running nose, cough and nasal congestion. Since last 2 days I have changed my hydration to 100 ml water every 45-60 minutes instead of complete dehydration. Though I did not get much relief, I am inclined to try it...
