Lack of sleep is a very common one. Stress and anxiety. Missing medication. Alcohol consumption.

Sleep deprivation.

Sleep deprivation, florescent lights (not flashing), and smells

My triggers are lack of sleep, stress , late on meds , over excitement, not feeling well and a few other things

Stress is my biggest but also sleep deprived and concentrating on something for to long and hard and heat exhausted and also being around to much drama could trigger a sezuire for me.
