Lecithin is not in my living intake of foods/supplements. It is not a suggested supplement when diet is corrected (fruits).... I feel it is too refined... My suggestion would be to include liver flushes and fix your diet to a mucous-less diet...
I think the twitching is due to parasites dieing... If its not it may mean I regaining nerve endings in places which were "plugged"... In any case I am certain it is a good thing... I have had it many weeks... I only notice it if I am relaxing, slight vibration/spazm....
