In August 2014, after I started doing an internship, I drank a double espresso
in the morning, like I always did, but
in about 3-4 hours when I walked out of my office, I started hyperventilating and felt like I was going to faint. Thankfully a friend was with me and I got a multivitamin juice and drank it after seating down. From then onwards I started feeling a little dizzy, but I could exercise normally etc.
