anxiety
"I was prescribed 0.25mg of Xanax for my hyper-anxiety and panic attacks.  As a 200lb man I needed a 0.5mg dose.  Xanax really solves panic attacks well, and noticeably helps with my anxiety.  It makes it much easier to fall asleep which is great at bedtime, but can be a real problem in the morning.  Reading "Feeling Good" by Dr. David Burns also really helped treat the thoughts that led to panic and anxiety."
