I cut out caffeine completely about two weeks ago. I got a screaming headache that lasted until I drank a real coke. I don't like headaches. I like Coke. I'm not going to try it again!
Patsie...I have Restless Leg Syndrome and Meniere's disease and caffeine is supposed to make both of these conditions worse. I have been drinking decaffeinated tea but still drink one coke a day.
I have gone caffeine free, as a book about Fibro told me to. I have noticed that I am not as keyed up or jittery, but I went probably from almost a pot a day to zero, very hard. Now I am used to it. I do miss it though.
