meimau,
f you are on a parasite cleanse then yes you will feel these movements, esp. if you dont have a zapper - i think...go to www.drhuldaclark.net for more information on parasite cleanses, and go to wwwdrclark.net for official web site and toll free number to .order. the person with the nickname "success" in this discussion, is really knowlegeable of a lot of conditions.
hope this helps.
