I am a graduate student and I am more than half way through with my thesis. I was diagnosed with epilepsy 3 years ago, and in order to control my seizures I take Depakote. Now my seizures are under control, but the medicine has side effects, which hinders my productivity at times. This hindrance causes delay in my work, hence I have a feeling that my thesis will take longer to complete but he does not fund my thesis.

Should I share my medical condition directly with my supervisor or should I first contact the disability center in my college first and let them tell him that?

**UPDATE**
So I spoke both with the disability center and my supervisor, and things worked out according to my expectations. Both the disability center and my supervisor were very understanding.

**Thank you all for your support and suggestions!!!**
