Now, solve this: After years of drinking Red Bull, Rockstar, Monster and some others, I have found the holy grail of energy drinks. It kicks in within 2-3 minutes and it lasts an entire work day. After seven hours or so, you gradually come down. There is no anxiety or disphoria when it wears off. You just get very sleepy when you finally rest. Redline Power Rush is the very best product on the market. If it were illegal I would buy it on the black market. 'Nuff said.
