TIREDDD!!!!!!

I'm probably just wishful thinking... But omg am I ever tired! I sleep a usual of 8hrs every night. Last night I took two caffeine capsules and went to bed around 830 forced myself to watch a movie till 1030 and I'm still exhausted lmao and hungry!!! I'll eat a full meal and still crave little snacks. Period due in 4 days so maybe it's pre period symptoms but hopefully not? Anyone else have similar cases or any feedback
