I think it MIGHT be your nose. I use CB-Advanced at 9% and the Tennessee Amish Harvest, Blackberry Sage, Blue Himalayan Poppy, Carribbean Holiday, Christmas Splendor, Cinnamon Bread Pudding, Warm Orange Gingerbread, Lavender Milk, Spiced Apples & Peaches and that new Pumpkin Souffle is to die for. They work like a demon in my - diffucult to get a super cold and hot throw soy...of choice. There are other good oils he has - but I don't have my notes at hand. Have you tried any of those oils?? I think Tennessee is right up there being one of my favorite suppliers.
