drunk, feel sick, poisoned, elated, spellbound
酔 centers on an altered state from intoxication: being drunk, feeling sick from poison, or being elated and spellbound as if under a strong influence.
酔 is the modern simplified form of 醉. The older form combines 酉 (sake jar) with 卒, which likely contributed the sound and the idea of finishing or reaching a limit, suggesting intoxication from drink.
The left side is a sake jar 酉, and the right side 卆 looks like a person staggering. Picture someone drinking from the jar until they become drunk and unsteady.
For スイ, imagine a drunk person swaying and saying 'swee' as they slur their words: swee -> スイ, and the sake jar 酉 is the cause.
