Narrative reference - Limitless

For my narrative outline, I have taken references from the film 'Limitless', as this story draws on many of the same themes as my own.

Limitless:
Facing unemployment and his girlfriend's rejection, writer Eddie Mora is sure that he has no future. However, this changes when a friend of his gives him a drug which produces enhanced mental acuity. He then becomes addicted to this untested drug, and rises to the top of the financial world. However, the side effects of this drug as well as Mora's dwindling supply threaten to collapse everything that he has managed to build.

In reference to this, my narrative includes:
- Protagonist struggling with job / making money
- Takes new, unknown drug
- Enhances mind / brainpower abilities
- Has fragmented memory / memory loss (In Limitless, it is suggested that Mora has killed someone but cannot remember doing so)
- Becomes involves with threatening rivals due to taking this drug
