Not very fond of the super maeng da. It makes me more sleepy than any other. I have to take like 1.5g to feel energy. More than that I just wanna sleep. I still have a couple of grams of that and I rarely want to use it because I'm afraid of sleepiness. Reds I never do because my past experiences with reds were always too relaxing and I need this for energy and focus. Maybe I should try again the reds to see if its different from my past experiences.
