You feel like a hole is being drilled in your head. Your stomach is heaving. You are sensitive to light and so confused that you can barely speak. Or perhaps you suffer nausea and a throbbing, one-sided headache that lasts for days. Migraine sufferers will recognise these symptoms. This essential book focuses on options beyond conventional medicine. By identifying a pattern of food intolerances and sensitivities, Sue Dyson offers the prospect of relief without prescription drugs.
