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?
Sounds like you are simply crashing your adrenals. If your adrenals are weak then it does not take much in the way of stimulants to crash them. This in turn increases the risk of allergic responses, which can cause the symptoms you mentioned.
