Yes feeling good right after Sugar and crap an hour after is typical of candida.
Candidiasis not only induce polyendocrinopathy.
2 different other things are at play in your reaction to sugar
1- it relieves you from your candidiasis induced hypoglycemia
2- mycotoxins induce all kind of hypersensentivity reactions. Your body may be sensitize to simple sugar. When you eat it you experience relief because you briefly mask your hypersensitivity to sugar. (mask/unmask phenomenons is well known to allergist). Mycotoxins will usually worsen your reaction toward substances you crave the most (moldy food, cigarettes, cheese, alcohol, pizza, yeast, sugar, fruits.) Candidiasis toxins create a lot of allergic disorder. These disorders usually target substances/food your crave for or eat too often.
