Buy choline, start eating magnesium,L-tyrosine, D-vitamins (double the dosage), Methylcobalamin 5000mcg a day, talk to your doc
and ask him to prescribe
ritalin (will probably aid your sleep).
Melatonin will aid your sleep if you have issues falling asleep. You probably also have issues in you nostrals, then a cpap wont help without proper medication.
Then you will need this.

If this regime fails then modafinil will assist you also.
