Vitamin C drinks may be one of the supplements many families would use as a quick remedy in case of mild discomfort. My family keeps Sensa Cools. Personally I do find it quite useful to boost my stamina after a night of shallow sleep. To turn this herbal tea into a refreshing drink, we can simply dissolve a pack of Sensa Cools in two tablespoons of boiling water and mix it with cold sparkling water, lime and ice.
