• Medications which would metabolized faster in the presence of thyroid hormone (Insulin, oral hypoglycemic agents and oral anticoagulants)
• Severe head tremors (which would impair the ability to perform VEPs)

• Corrected visual acuity worse than 20/50 in either eye or other eye issues that would prevent reading of a standard eye chart
• Head tremors or other tremors that would prevent sitting relatively still for a vision test
• Patients taking proton pump inhibitors (PPIs) or H2 blockers will be excluded unless they can safely not take these medications during the week of study drug administration.
• Patients taking Ampyra (dalfampridine) will be excluded unless they can safely not take these medications during the week of study drug administration.
