Coffee and Caffeine FAQ

I think it would be best if i was under medical care at this point. I have not had any caffeine since Monday. I was drinking 3 large cups of coffee, at least 2 energy drinks plus a shot of the 5 hour energy stuff not to mention all the tea an diet cokes i sucked down. So needless to say last night was the worst. I literally thought i was dying and had no idea it would be this bad. I was sitting in a meeting at started getting a massive headache. Soon to follow was cold sweats, shaking, and more of the worst headache i have ever had. While on my way home (a one hour drive) i had to stop 4 times to throw up. Sorry to be graphic, but i thought for sure i had food poisoning until i found some other comments on this site.
The quiting of caffeine was brought on by my nutritionist who suggested i wasn't losing the weight like i could be if i quit caffeine. Wait till i see her again. This is the worst thing i have ever gone through.
Any advice would be great to get over all these symptoms without taking caffeine or any drugs with caffeine in them.
So i guess what i need is rehab for caffeine addicts. I certainly can't function like this.
