Don't Blink

I become withdrawn when I feel ill. I am very sensory-defensive, so any extra stimuli on top of the illness seems magnified because I'm already so overwhelmed. So I wouldn't say I felt "less autistic" on Atkins, but my sensory difficulties were not as pronounced. I still had overwhelming urges to read for hours on end, a strong aversion to social situations...

I'm wondering if someone here can point me in the right direction. I'm making an appointment with my doctor tomorrow, but I want to make sure that I ask the right questions and request the right tests. I am a 28 year old woman. I have always had digestive difficulties that resemble IBS including lactose intolerance. I am always sick to my stomach...
