I appreciate your efforts to quit the habit. However, Ice or crystal meth
is abused quite often by people than any other drug.
It would be difficult for one to quit it with will-power alone. It is better to seek a professional's advice. You need to be de-toxified first and then the rehabilitation
should be done.
There are various rehabilitation centres that work on this. In a group, it would be easier to kick the habit. You can enrol yourself for the nearest Narcotics Anonymous (NA) body and start living a normal life.
rush will slowly go away.
Please make an attempt to speak to the people closest to you, who can help you out in this.
I wish you recover early and lead a beautiful life ahead.
All the best.
