Curious what you are eating for breakfast? (If you feel like sharing) Sorry you're having these, they sound annoying!!
On the mornings I was going to class I was having an instant breakfast type thing instead of something more substantial like I usually have. My thinking was that I didn't want to eat something right before I went to class but drinking something would be fine. But I'm sure there are tons of chemicals in those things and perhaps I'm reacting to one of them. The obvious solution is to get up earlier so I can eat earlier and not have it be an issue.
Hmmm will be interested to see if this helps. I used to get them and they were sometimes triggered by bright light.
