Yes, the same thing happened. I am getting blood tests done for caffiene allergy at www.directlabs.com and see if that is the problem. Apparently when you stop all caffiene it floods your system and can cause toximia. I am having the "CK" test done on Friday to see if that is what it is. It only costs $34.00 to find out for certain so I think it is worth it. I am 44 years old and have had coffee every day since I was 9 years old that I can remember. My parents probably put it in the baby bottle too. They were not real bright. I hope this is it. I really neeed to lose weight. I am 50 lbs over weight.
