Well certain conditions must apply. Some times children get hyper before when their blood sugar is low. Ginseng in massive quantities all at one time can make it so. You have to have a singnificant dose too. Amercian ginseng is shit. Asian ginseing is the shits!, much less is required. If you have high receptors in the brain and low nerotransmitters, like me, it willl give you a kick ass high. If you have this setup you are also more vunerable to addiction, and my father gets drunk alot. I am there for at risk for alcoholism, which I will not bother, even if a little bit improves health. I guess if you sleep deprive yourself you are more prone to hyperactivity. I am, you know that. If they don't tell you how much is in the can then its probably too low. Ginseng should only be used for a certain amount of time and then a brake exept in the elderly. I think it was asian ginseng that could be use for 2 wks on end followed by a 2 wk brk.
Take more stimulant herbs.
You want to calmn down, exercise, that will do the job.
Get in shape, its twice as fun to be hyper and in shape, that way you can do back flips all over your front lawn.
