What are the withdrawal symptoms of doing crystal meth?

Dependence to crystal is purely psychological, you will FEEL as if you need it, hungry if you will, VERY tired and no energy at all when awake, but you will get over it fairly quickly if you can beat the urge to use. You only THINK you need it, because you have used it so long your body expects it, but getting over it is not much different than quitting smoking. Expect to be pretty hungry though.
