I've been wondering this for awhile. I go for the caffeine when I wake up or when I feel like I need a pick-me-up. But sometimes I think it makes me EVEN MORE tired! I just drank an iced coffee that I made and now I feel like I'm about to fall off my chair! I'm sooo drowsy, it isn't even funny. I was mildly tired before I drank it but now I'm realllyyyy sleepy. Have you ever heard of this happening before? Can caffeine make you more tired instead of more alert like it's supposed to?
