Caffeine and it's effects

Whenever I have caffeine my nose runs a little bit. At night or when it wears down I start to feel a tingling sensation in my hands and fingers. When I wake up in the morning my nasal passages will be clogged and I feel completely hungover. I drink plenty of water and fluids to try and replenish but I feel like this every time I have caffeine.

What is happening and what does it mean with this? What is causing this reaction? Tweet
