Same from my experience, except staring at the ceiling had effect -- it made harder for me to fall asleep and instead of getting to bed at 3-4am and falling asleep almost instantly, I got to bed at 1-2am and fallen asleep after 5-7am. Tried it multiple times for week-two. Never again I will do this mistake.
