Hi Monique, It might be worth getting a threadworm dose from the chemist - it would be a different formula from the Humaworm. Also get a magnesium suppliment. Worms take our magnesium, and muscle twitchings can be caused by low magnesium. Sometimes I take a teaspoon of Epsom salts [magnesium sulphate]in warm water when I feel low in magnesium.[It's very inexpensive] But a magnesium citrate suppliment is more pleasant to take. Please keep us posted. Love and light, Deotima.
