1-2g Phenibut, 300mg Adrafinil, and 200mg L-Theanine with 1-2 cups coffee and morning snack. Thoughts?

I haven't tried them all at once. I would take in the morning, no later than 9am. Aiming for productivity at work and school while having the ability to hold conversations with coworkers and other law students. Ideally, my stack can help shoulder the load of my last year in law school and work during bar prep too.
