Tea usually doesn't have enough caffeine......try caffeinated coffee for a full dose of natural caffeine or take a No Doz pill for pure synthetic caffeine at any store. Though you really don't need to since mushrooms are a stimulant anyways, but I wonder whether you could really dissolve mushrooms in coffee.
As far as i know theres no stimulant to psilocin. I'm not sure of the chemistry. but i know lsd has a stimulant effect, i think because of an oxygen aton on it. again, not sure, but i know I've never felt speedy on shrooms
LSD gives me more energy than cocaine. And it's more "real" energy than like jitteriness and forced social lubrication.
