After I put in eye drops, I need to keep the head still and in a state that it is fixed at a tipping position for 2 minutes so that more drops get into my eyes and don't come out too much.
The verb "tip" or "lean" are action verbs which means to move the head into a slanting position.
I am not sure if we have any adjectives deriving from the verb "tip" or "lean".
We have the adjective "still". I can just say "keep your head still" (keep something adjective). But it is partially correct as I need to let people know my head is still at a slanting position.
Or I can just say "tip your head far back and then keep it still in that position".
What about "keep your head tipping far back"? It sounds like the head keeps moving to the back repeatedly.
