Slowing down the drive motors

[anthonygraff24]

My team is using the standard gearbox for our drive train and with two motors on each side the wheels move way too fast. I'm using the standard tank drive code with two joysticks for driving. The way it is now, unless the joystick is barely pushed forward the robot kindof goes out of control, there is a lot of torque, and the robot shakes too much for comfort. Is there a way to code the robot so that I can still use a standard tank drive but slow the motors down? I hope I'm being clear enough as to what the problem is but I can clarify if I'm not <3
