its a stage you have to go through in order to get good at something. i found using alternate tunings far far easier than using standard (when tuned to an open chord), even when i had no idea of where i could play on the neck, or what would sound good.
i have found when playing guitar "normally" i "think" with chords, i.e. not really melodically or rhythmically. but when i get a slide my whole style becomes based around rhythm, i often knock out the beat on my acoustic with my hand whilst playing meaning that there are far more gaps inbetween what im playing and gives a very rhythmic feel. an example of this type of playin is from ben harper (in open e as well!) its called " when its good" if ya listen to it you'll notice how it is all based around the beat. i found this to be very different to everything else i've ever played an opened loads of new stuff up wich i wouldn't have thought of otherwise
