I'm addicted to ketamine how can I stop?

Seek help. First step is being motivated to stop. Glad that u r there. Talk to your doc. Next step is safe detox. Then the hard part will begin. Delete phone numbers of all your using friends from your phonebook. Change your phone number so they can't call you. Join a 12-step program. Replace your habits and rituals surrounding the addiction with positive ones. Depression treatment may be needed. Good luck!
