ginseng is a good herb, but to remain effective you have to use it for two weeks and then take a two week break because your body will adapt to very quickly ,my sggestion is to wean off the coffee start drinking green tea instead coffee it has 1/4 the caffine and is high in antioxidants and eventully wean off green tea as for the ginseng ,between your two week break of ginseng you can take an herb called (holy basil) it is an adapagenic herb like ginseng and has calming energetic properties ,you can find it at most GNC stores( good luck)
