I was on 0.5 mg of Xanax twice daily and I started having panic attacks, so I increased my nightly dose to 1 mg (my psychiatrist said I could change things up a little bit). Then after 5 days or so, I went back down to 0.5 mg at night, as the Xanax was making me too tired. Will I experience any withdrawal symptoms? I wasn’t on the increased dose for very long. Unfortunately my psychiatrist is away for 3 weeks, so I can’t ask him.
