Drinking Tea can have a better effect caffine wise.
Good black or green tea is not just loaded with antioxidants, but due to the tannins and other chemicals the caffine is released much slower.
Coffee or tabs will give you a hit that may last a 30-60mins, but tea will extend to a few hours.
Also noting Caffine is an antidiuretic, meaning it will make you pee lots and degydrate your body.
Raises blood pressure, increases anxciety, and aggression, you will get jitterey, and lack focus aswell..not all of these are that bad i guess!
Your body willl also very quickly buidup a tolerence to it...and will feel very flat when you stop having it..
