3, 2, 2, 2, 2. on the 3rd puzzle, i found the 3rd difference which is the eraser right after about 1 second after the bell ringed and time ran out. so that doesn't count i think. today, i got enough sleep i think. maybe i overslept for 1 hour more today which should make up for yesterday 1 hour short of sleep. but combined with 5 days ago, i still have 5 hours short of sleep.
