Tea that helps with alertnes without caffeine that works the first time I take it?

Not all herbs take a month to kick in, even ginseng bud kicks in right way for me, not the root though. Mate tea has a caffeine like substance and works well or better than green or black tea. It has a cult like following similiar to coffee. I like it but too much and I get a weird headache. If you need a real rush try bringham tea which has pseudo-ephedra in it.
