I never drink coffee cause i do a mild case of the jitters and feel uncomfortable, but because i was extremely tired going into work at 7am, i went to my work cafeteria and drank a cup of coffee. About 15 minutes after I drank the coffee, I started to feel this intense heat and pressure in the back of my head followed by extreme paranoia, fear, anxiety, crazy thoughts, and a fear of not being able to control my body. I was really scared and didn't know what to do. I have never in my life experienced this and the only thing i can think of that could come close was the few times in my childhood when i experiemented with marijuana. Seeing that i don't like the feeling, made drugs never an issue or temptation for me. I started drinking a lot of water thinking that i was getting delusional from dehydration, but that wasn't it. I tried to sleep it off after work, but even this morning i still feel it, but definitely a lot less then yesterday. I am really curious if this sounds like just anxiety, high blood pressure, or maybe even my coffee being spiked with drugs or something. If anyone has an idea, I would love the health seeing that i was so scared yesterday and would like to never experience this again.
