I honestly feel I have no control over my absence seizures because sometimes there isn't a known trigger present, they can happen any minute of the day without warning. I know to expect them in certain circumstances but I cannot tell exactly when. When I am walking to work first thing in the morning I have many seizures as I am still half asleep and I know to expect them late at night, the other day I walked into the doctors surgery and for some reason they had a bright floodlight pointing at the entrance, this caught me by surprise and I had a seizure straight away. I appear to have several triggers, some that I am still discovering the latest being noise in the office and reflections on the glass in pictures hanging on the wall.
One thing I have worked out, is that when I am concentrating on something really hard I do not tend to have seizures, like horse riding, riding on the back of a motorbike or even simple things such as pouring boiling water from a kettle.
I find that my absence seizures can happen at the most embarrassing of times and there appears to be nothing I can do about it, coz I get no warning I don't get time to prevent them.
