hangover
酲 centers on the unpleasant aftereffects of drinking too much alcohol: a hangover.
酲 combines 酉 (alcohol) with 呈, which likely contributes the sound and may suggest presenting or manifesting the effects of alcohol.
The alcohol radical 酉 on the left and 呈 on the right look like a bottle presenting its aftermath: a hangover.
For テイ, imagine taking a tea after a hangover: tea -> テイ, and the tea soothes the alcohol's effects.
