So I firmly believe that I have been getting headaches due to caffeine withdrawal, but they always seem to happen in the evening. Last week, I went two days without having any soda at ALL... and for those two days, I got severe headaches every evening that wouldn't go away, even with meds. After getting some more soda, I was fine. Then last night, I drank the last pop. I was fine all day until this evening, where I started getting another throbbing headache for no apparent reason. It's not going away. :frown1: I just went to the gas station to get a soda to see if it would help. How in the hell can you stop caffeine headaches from lack of soda? If I quit drinking cold turkey will they eventually go away? These headaches are almost debilitating... I get mildly dizzy, and I can't concentrate on anything. Help!
