Hi Ocean! i have the cold spells on and off, and maybe it is worse when I'm going through a cleansing period although I haven't kept track of that in particular. When a person's thyroid isn't doing all it should that particular day, the person feels cold despite the temp of the room. But what I can tell you is this: i've read several sources, including the story by _Bob in many CureZone Forums , stating that using cayenne pepper in some water helps this. You start with a small amount, swish the cayenne pepper/water mixture in your mouth for a bit and then swallow. it has helped me with this problem. -North
