Should i be concerned?!
Question: Should i be concerned?
I am not really sure of the items you listed. But, for some I have knowledge.
Craving for items like plaster, chalk, toothpaste could be related to calcium deficiency. These days calcium can be accurately tested through blood tests. Otherwise, to be on the safe side, please make sure you are taking ample milk, or any other form of calcium. Then observe if you still have the same cravings.
-- Another thing: Sometimes mineral deficiency should also cause cravings. Like craving for alcohol.
-- Lastly, it could be hormone related. At different times, you may crave for different things based on hormone levels.
I love smelling washing powder a lot
and I used to love licking toothpaste when I was little
