Anxiety
"Began 10mg daily. First day was difficult. Severe mood swings, heightened anxiety, baseless anger, etc. Advise anyone beginning this to 1) begin on a day off and 2) have someone around to keep an eye on you. That ended at the second day, when I only took half-pills. Now that I am a week in, taking the full 10mg and things settling down nicely. Yawning is annoying and my normal night-owl life is riddled with deep, restful sleep, but I am calmer and less angry all the time."
