Lui,

The caffeine sounds like it is for the migraines only. It may help the migraines. I am surprised you have not tried sunglasses sooner. We must have missed that.

I am not supportive of the push through school work but getting wired on caffeine might give you a need to do something.

Focus on getting the head aches under control first. Then attack another symptom.

The running may be to push through the vestibular struggles. Has the vestibular therapist tried the Epley Maneuver with you ?

How often have you been going to the mall?
