Open Question: Xanax addiction? Caffeine Addiction?

Psychedelics as a huge fan, I began my trip to 5 mg over 6 Xanax Zhi. Recently back to reality, when I go to school and work to keep awake, I have been focused on serious problems, let alone than normal. I got my dizziness and insomnia is more serious, it once was. I also quit caffeine in there to help. Whether or Xanax, or to cause these symptoms caffeine problem?
