Find your self destructive behaviour and neutralise it. If you keep jumping to twitter, block twitter. You'll subciously open a new tab, the connection will die and your conscious mind will be prompted by the change in sensory input caused by the unexpected block. At this point stop, stare at the screen, vocalise 'no, I'm in work mode' then wait another 5 seconds, and slowly flip back to the work. Changing perspective helps for me too, listening to music 800% slower, and using timers to enter state helps focus my mind that something important is going on. Hope that helps!
