Hello, Lain. What study methods to do use to enhance your academic endeavors and promote better retension/comprehension? Does it invole the use of stimulants and/or nootropics? Any nifty little "lifehacks" hiding up your sleeve? Post it all here!
Personally, I prefer to study outside of the house. Although studying in bed is comfortable, your brain is so used to seeing your bed as a place to "relax" that it can subconsciously hinder you from functioning effectively. Being somewhere that screams "time to work!" to your brain is oftentimes an enormous boon. I normally frequent coffee shops when studying (the coffee itself can also be a nice mild stimulant).
If you have trouble concentrating don't be afraid to experiment with stimulants such as adderall. You may very well have an undiagnosed case of ADHD. I have a diagnosed case, and Adderall works wonders for it. I've never tried modafinil or adrafinil, but I've heard they can be great as well not only for ADHD sufferers but also people looking to study more effectively in general. If you're studying for a test it might be to your benefit to also take Adderall/Modafinil before the test.
I prefer to listen to music when I study, without words as the words can be distracting. Ambient stuff, Vaporwave stuff like 2814's Birth Of A New Day, or just recordings of rain/thunder.
In addition, I've gotten mildly positive results from using Spritz/Spritzlet in the past. Give it a go sometime, it just might work wonders for you. And imagine how fucking /cyber/ Spritzlet will be once it can run one Google Glass/other augmented reality headsets.
