Yes! I wake up sometimes with my heart pounding, and nervous as all heck. I have panic attacks occasionally, and am a high strung person naturally. I used to get panic attacks that woke me up at least 3 times a night. Also night terrors. Thankfully I don't have them as often now. I would have certainly ended up in the hospital if that had continued. I was getting no rest and no sleep. I'm on the extended release Xanax now, which helps tremendously.
