I'd suggest visiting the headache forum and the epilepsy forum. While they may not apply directly to you, you will find the symptoms are similar with many conditions.

Few questions:

1) Have you had an EEG?

2) Could you explain the abdominal pain in detail? As in, is it an achy pain; a gassy pain, etc. (I swear, this actually has a reason behind it)

3) What are you taking Depakote for? I want to clarify they didn't give you this for a headache.

4) How long do your headaches/migraines last (from start to finish)?

5) Do you have any pre-warning signs (auras) to warn you they are coming? If yes, what are the signs?

6) Have they tried Butalbital (Fioricet) or Relpax?

Thanks!
