A 24 y/o male was brought to psychiatry emergency. He appeared very excited, and was wearing orange t shi and pink pants along with googles. On seeing the doctor he said- 'I am the ultimate doctor, i have done MD and MS in all the specialities and I can cure all the diseases'. The family members repoed that he has not slept in last two days and was saying that he is trying to find the magic formula to reach moon in one hour. What is the drug of choice in this patient?
