I would hire a great attorney, buy some land, quickly build a house, pay somebody to source some N, store it safely and hidden, and then live well. After getting my fill of that lifestyle I would take the N where I choose and with my attorney and a doctor there to make sure things go right. I would have made a trust to use the remaining money to fund an organization that would fight for every human's right to die just because they choose to, including the mentally ill who are discriminated against. It would also operate a facility in a country that would allow it to operate legally to assist people to die by using N or a new improved version of a suicide drug.
