be hyperactive, have difficulty sleeping and have stomach or bowel
disorders. Very few people may get panic attacks, hallucination,
unusual perceptions such as itching, tingling and numbness, and

confusion, delusions, change of perception of the own personality
(depersonalisation), and change in perception of reality (derealisation)
