slip of tongue

i have this problem of slipping tongue... often we're paged by ward nurses and we get to answer them... skilled people wouldn't give a hint where they are and what they're doing... they just talk like "ok", "coming soon" and that's it... but for me, there's this tendency to tell people where i am... instead of "i'm coming"... i usually say "i'm coming up/down/over/out"... i tried to remind myself not to mention the "direction" but i just can't help...
