i kinda want to try focus/concentration pills

im bad at focusing on stuff i dont want to do and get pretty distracted easily. so what ive been thinking about for the past few months is, what if i try focusing pills? im definetely sure that pills of these kind exist. but really, dont i need to like 18 to buy them from a pharmacy? or one of my parents. i dont want my parents involved though. ugh. mannn... maybe this focus issue is because of my lifestyle. and i dont need them. maybe if i actually sleep well, eat well, excercise well, get back into meditating or surfing the internet less, then per chance i can focus much easier. 

it would be nice if i tried them though.
