A physics analogy would be “imagine you could go back in time. how much energy would it take to get to 1983?”. Just not complete or useful enough to discuss.
The minimum energy required is ~1,000*(Your mass in kilograms + the mass in kilograms of everything coming with you) petajoules, assuming you want to get to 1983 in about three months of subjective time, with a gross of assumptions about the way time works. A minimum of 200 joules per kilogram will get you a subjective arrival time of 1.2 million years. [ETA: Forgot about deceleration. 400 joules for the 1.2 million year mark.]
