with porn it is self-regulating. i can only jerk off at most about 5 times a day tops. that means even if i have nothing else to do i will not spend more than half the day jerking off because i will reach a point where it just becomes unpleasant.
but with Twitter i literally had a reflex where whenever i would reach with my mouse cursor for the bookmarks bar my hand would automatically click on "X" regardless of what i actually needed to click on. for example when i would try to go to my own site ( which is also on my bookmarks bar ) more often than not my hand would just end up clicking on X because it was already in my muscle memory so to speak.
so when i do my detox the first thing i do is remove "X" from the bookmarks bar. this way when my hand reaches for it and it's not there i am reminded that i am detoxing.
