You know what works really well for me? playing scales linearly up the neck in three note groups, first playing two notes fretted normally then pre-bending into the third, then playing the same three notes fretted, and moving up one position and doing it again. For example:
G|--2-4-(b)5-4-2-4-5-4-4-5-(b)7-5-4-5-7-5-| etc.
something about that really loosens up my fingers and in addition helps keep your bends sharp.
then i just wank around aimlessly for a while, drink a gin and tonic or three, and flirt with groupies, if any exist.
