stop giving yourself excuses to keep procrastinating- when you realise you’re faffing about on the computer- if you’re motivated enough to actively reach for the bottle, get up and get a drink of water, and physically take your adderall, i bet you can muster up the motivation to not walk back in the direction that you came from (ie: that f the computer). the pills only HELP you focus- they don’t control your arms and legs, they just make a you a bit more receptive to focusing on doing what you wanna do….if you decide that you really wanna hang around online until you feel the urge to do otherwise, you’ll just be really well focused on browsing for a few hours while the pills are working. 
now, if i could just pry my fingers off the keyboard….. i’d take my own advice. if i had adderal, that is.
