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.
