Cleanses always will bring a herxheimer reaction of some degree, which means, you will feel sicker. Feeling sicker is actually a good sign meaning that critters are dying and your cleanses are successful. Dying candida and parasties always make you feel terrible. There is no way to avoid a herxheimer reaction so do not feel you went too fast. You can however decide to slow down to lessen the herxheimer effects. Good luck and you have the support here to get you through.
