Welcome to HCM
We understand your concerns
I went through your problem descriptions. You have nothing to worry as the problem you are describing is quite normal after a tiresome and tight schedule. Just go a day or two back and analyze the happenings. You should know the reason for this.
The justification for this is pure stress
. Anxiety induces hunger pangs as it is related with the acid secretion. Just don't worry, otherwise it might come back. Do visit a physician if it is relapsing again and again.
Hope this clears your doubts. Available for further clarifications.
