Coffee and Caffeine FAQ

about 15 hours ago I stupidly had 4 No Doz caffeine pills washed down with a glass of coke. an hour later had 2 more and then another hour later had a very strong coffee. And that was enough to give the most horrible night of my life.
I couldn't sleep, my heart was racing i thought i was going to die. My muscles were spasming and at one point was unable to move my neck for several minutes. I had the most terrible diarrhea and was lucky enough to be able to hold back from vomitting.
The whole night seems very vague and I think I had some hallucinations.
My heart still seems to be beating a bit funny and having some twitches and also diarrhea but not nearly as bad as before.
It is a very very scary experience so everyone should know that it doesn't take much to give you a horrible caffeine overdose especially if you usually don't have it often.
I hope all the effects of it are going to stop for me soon!
