I don't know that the mixed part happens so "rarely." I've also experienced terrible mixed episodes with sky high energy but no fun. Dreadful anxiety, and highly argumentative. I was so terribly sensitive to noise and hardly slept. At that point I lived near a very busy street that was (and still is) notorious for "Sunday Nite Cruising." Loud engines roaring, mufflers popping, people sitting in parking lots with ghetto blasters blaring out insanely loud music. It literally drove me crazy, although it didn't bother my roommates at all. One night I went out on the street and started screaming at everyone to F-off. I used every profanity I could. I was a raving lunatic. And during that time I was quite suicidal, and fortunately I voiced this to a friend, who took from me all my sleeping pills but what I needed for a week or so. This was before starting quetiapine, as I resisted that as long as I could.
