Drawt or Draft?

     After I wrote the lyrics to my new arrangement of the hymn "As the Deer" I realized that I didn't know how to pronounce one of the words. It's "draught," meaning the act of taking a drink. I've been pronouncing it "drawt," but I only now discovered that it's supposed to be "draft" or "droft!" Apparently, I'm not the only one who's confused. There was quite a conversation going on on answerbag.com. Now I even more don't know what to do! Go with what I've been saying, or use the dictionary pronunciation that most people don't know?
