After a sleepless night, she went to work feeling totally muddled.
Tips
usage
The 涨 is read zhàng (the 'swollen' reading), not zhǎng. A common variant form is 头昏脑胀 — same pinyin, 胀 in place of 涨. Both forms are interchangeable in modern use.
mistakes
Don't read the 涨 here as zhǎng. The zhǎng reading is for things going up (prices, water levels); the zhàng reading is for things swelling outward (a head, a belly).
