Hi - thanks to you all for your responses.
My sister was on the lowest dose (whatever that is???) of Ignatia which was prescribed for 10 days. She took 2 pills every day for 5 days (she started feeling bad on the first day of taking them). She was also given Pulsatilla in reserve - these were not used.

Also, does anyone know of anyone who has successfully overcome M.E. and by what means?

Thanks again.
