After acquiring some Modalert, I have managed to find the right stack for me:
1. 200mg Modafinil (once a day, twice maximum, with doses spaced out)
2. 1.6g Piracetam (three times a day)
3. 1.5g Oxiracetam (three times a day)
4. Choline Bitartrate Inositol (for now, until I get an actual choline supplement from GNC later)
I don't normally take Piracetam and Oxiracetam at the same time, but will whenever I have a lot of homework to do. The choline supplement might change, but I still have those two racetams.
This stack will be my main stack for my last quarter in college, as I am taking six courses (one Chemistry, another Math, another History, another Computer Science, and two Kinesiology courses).
Look at your study habits as well, you shouldn't need such a large pharmaceutical backing to help you get through school. If you don't like your program you can change it yknow, you'll prolly make enough money to be happy in whatever you do decide to study. No point finishing a degree that makes you miserable then getting a job that makes you miserable.
