‘Being spared the effects of alcohol’ could indicate that Vulcans aren’t affected by it. Their blood chemistry being different may mean their bodies don’t metabolize alcohol the way humans’ do, and so there’s no hangover because of the lack of metabolic issues.
Not drinking enough to get hungover/at all technically ‘spares’ one from a hangover, but that phrasing would be strange and clunky. It’d be like telling someone who just got sunburned at the beach that “I never get sunburned at the beach” to convey that I don’t go to the beach, when just saying “I never go to the beach” is a direct statement that logically precludes sunburns from beachgoing.
