Probably really stupid but it's my second time having an energy drink and the first time I had no problems but this time I have experienced nausea, upset stomach, I can hear loud thumping sounds in my head I can't sleep and more, everything I've read doesn't help so I was wondering does it eventually wear off so I can sleep and the nausea eventually go away or what happens? All I've read say I'll die but I highly doubt that ((I've tried to see my heart rate but honestly I can't feel it)) And I thought drinking water would help but it makes me feel sicker is that normal
