Feel terrible to know what your daughter is going through. My son started on the rife/coil machine 4 months ago. At first, he got no reaction in using the machine until we found out we were using it incorrectly. Then, only after using the machine for 15 sec. he began getting reactions. Then I knew he was responding the way he should. He is now using it for 28 minutes at a time and gets sick that evening or early the next day. Some of his symptoms are even worse after using the machine than before rifing. From what we have learned, it sounds like your daughter is responding the way she should after rifing, however, we don't know anything about the type of machine she is using. Make sure she drinks as much water as she can just before rifing.
