GOOD LUCK but maybe a 100% sativa might be safer.

Modafinil’s side effects include severe migraine, intense fear and anxiety, excessive adrenal gland overproduction, and nausea. Serious side effects in high doses include delusions, unfounded beliefs, paranoia, irrational thought, and intense, temporary depression, possibly due to its effects on dopamine receptors in the brain, as well as allergic reactions. The amount of medication used should be adjusted in those with kidney problems, as this medication has markedly increased side effects during renal insufficiency.[14]
It is not recommended in those with an arrhythmia, significant hypertension, or left ventricular hypertrophy.[14] Modafinil appears to work by acting on dopamine and modulating the areas of the brain involved with the sleep cycle.[3]
