I think its very normal for a non-drinking alcoholic to be repulsed by the smell of alcohol..bout as normal as an ex smoker disliking the smell of cigarette smoke.
On the other hand..I haven't smelled of alcohol since I quit drinking. Unless he's got some really seroius diabetes that is left untreated, there's no way he smells like he's been drinking if he hasn't.
Go with your gut.
