Lifelong adderall (dextroamphetamine) user.
Low doses (5-10 mg) will give you the ability to sense fabric composition by touch. Continued use at this level will give you a taste for alpaca.
Medium doses (15-20) will greatly increase your desire to play Visage in Dota, and the patience to get good at Visage in Dota. You will not get any better.
High doses (30-40 mg) can trigger meth psychosis which is when you become close enough to god that you can see the riggers rigging
Very high (40-50) opens your third eye. You also immediately start shaving your (very large) collection of alpaca clothing because it matted
Anything higher will make you vibrate into Niberu, which is like agartha but everyone there are liggards
