Well todays market is a competitive one, with entreprenuers trying to do anything to sell their products. Thums Up is one of the products which is very badly marketed.Pepsi and coke have gained the lead due to their excellent marketing and the standard they have maintained in quality of their drinks.
The main drawback of this drink is the amount of gas it has. After drinking it you would completely be filled with gas and the DAKAR would become a routine affair for some time.
Instead of these drinks I would recommend the mangola, limca and other such drinks which are not bad for the health.
