From what I've read in an article in the Developing Healthy
Habits newsletter, inhibiting cholinesterase will increase your
symptoms, because cholinesterase is what makes your muscles
flexible. Fruits and vegetables in the nightshade family contain
Solanine, which is a powerful cholinesterase inhibitor, which will
interfere with muscle movement. Nightshades include tomatoes,
potatoes, eggplant, blueberries, peppers and tobacco products.
