As for the Xanax, it's okay to take it with juice, there is no interaction. However, really make an effort to space out your dosages, as xanax is a fast acting benzodiazepine(minor tranquilizer) and it's half life is short. So, basically it can become very addictive, trust me you don't want to get addicted to any benzo, it's terrible when you're coming of it, you have what's called rebound anxiety and it's worse than the anxiety that you were originally trying to treat and try not sleeping for two weeks. I'm not sure about zoloft, but, as stated above others on this board have used it apparently with no interactions. Paxil is good for anxiety, it can be used in two ways. The first way some people use it is two take half of a 20mg pill (pink) when they feel anxious. Others use 20-30mg daily to treat persistent anxiety, but don't forget, the effects of reduced anxiety will only start after 3 weeks of taking the drug daily. Hope that helps you out.
