Hi Laura,
I have had a number of occasions when I suddenly switch on whilst unmedicated. I have posted about it before, but have not found anyone else who experience it. It happens either on getting up from bed or when my meds have worn off. As I mentiomned in another thread, the phantom "on" seems to be initiated (but not always by eating. The longest on time I have seen is 90 minutes.
Very pleased to see your post, I was starting to think it did not happen to anyone else.
Ron
