Yes - I can make him a formula without the cayenne. Just order as ususal then email me firstname.lastname@example.org and I'll make it for him. Not to scare you or him, but I think he is having die-off reactions if the HUMAWORM kept him awake all night. If he cannot handle cleansing at this time, then slowly start him out on the 7 anti-parasitic herbs in his daily food. 1/4 teaspoon of each per day: onion, garlic, sage, thyme, ginger, cinnamon and cloves. Just put them into food - for example: ginger, cinnamon and cloves in oatmeal or applesause and the others in rice, potatoes or on baked chicken. You can just use the powdered ones found in any spice section of any grocery store. These alone will not kill off all parasites, but they will not cause resistance AND they might help his body slowly get into a detox mode. When he becomes adjusted to these daily herbs - then he might be ready for a full 30 day (cayenne free) cleanse.
Oh, and you can be more liberal with the onion and garlic powders if he can tolerate them.
