As an expert sommelier and brewer, I can confidently say that it is highly unlikely to get buzzed off O'Doul's or any other nonalcoholic beer. The reason for this is quite simple – the alcohol content in nonalcoholic beer is extremely low.
To put it into perspective, O'Doul's has an alcohol content of only 0.4% ABV (alcohol by volume). This is about one-tenth of what you would typically find in a light beer, which usually has an ABV of around 4%. So, even if you were to consume a significant amount of O'Doul's, it would still be challenging to reach a level of intoxication.
Nonalcoholic beers are specifically brewed to have minimal alcohol content, usually through a process of brewing and fermentation that limits the production of alcohol. This means that the beer is designed to mimic the taste and aroma of traditional beer without the intoxicating effects.
In fact, the alcohol content in O'Doul's is so low that you would need to consume an excessive amount in a short period to even come close to feeling any buzz. It's important to note that excessive consumption of any beverage, even nonalcoholic ones, can have negative health effects, so it's always important to drink responsibly.
Personally, I have tried O'Doul's on several occasions and found it to be a suitable alternative to traditional beer when I wanted to enjoy the taste without the alcohol. It has a similar flavor profile and can be quite refreshing, especially on a hot summer day. However, it never gave me any sort of buzz or intoxicating effects.
To summarize, nonalcoholic beers like O'Doul's have such a low alcohol content that it is virtually impossible to consume enough of it in a short enough span of time to cause intoxication. The 0.4% ABV in O'Doul's is significantly lower than what you would find in a regular light beer. So, if you're looking for a buzz, you'll have to stick to traditional alcoholic beverages.
