Anyone feel like their partner is not really "present" when that person is drunk/high?

Does anyone else feel like when your partner gets drunk/high, that they're not really "there"?

Such as your partner is there in body absolutely, but somehow their dramatic mood change and behavior change puts this weird feeling in the back of my mind that I'm more of a babysitter/bodyguard at that time trying to make sure my partner is still okay and nothing bad happens--it's not spending time together, because they're not present in mind and instead of a date it's babysitting.
