Is this normal while drinking

Mentally I feel completely sober. Obviously drinking and driving is bad, I would never ever do that stupid shit, but mentally I feel like I could drive (I won’t ever do it don’t worry). But then I stand up and try to walk and realize I can barely even do that without stumbling. Like mentally I feel sober but just relaxed, I feel physically drunk though. Is that just what being drunk is like or is it just me?
