NA beer is one of the only carbonated non alcoholic drinks that doesn't taste too sweet. That's why I drink it sometimes, not because it reminds me of alcohol. I find it easy to drink just one or two. It's a personal thing. If it triggers you to drink for real then don't do it.
You may also want to try non alcoholic ginger beer (which unlike NA beer isn't really beer and contains no alcohol at all). Some brands like "Q" are very refreshing and not too sweet.
