It was confusing because you showed a bag of freeze dried worms so that's why we mentioned it. Don't feed her late in the day, that gives her tome to digest any food, they need the heat for at least 3 hours while the basking lights are on to digest meals, sometimes even longer. If a beardie vomits it doesn't mean they have parasites, although many beardies have parasites anyway. It's good that she has eaten again, she's probably fine now. I don't think you need the OTC Worm Guard.
