Aspartame and headaches?
I'm a month into keto. I know some say not to use any artificial sweeteners, but I'm in the position I'm in to go on keto in the first place bc I was addicted to soda. I can't just go no flavor overnight. Anyway, I've been drinking one diet coke (Coke zero tastes awful to me) and several glasses of crystal light every day. I've had a terrible headache for 3 days now that won't go away. I'm new to aspartame, and wondering if anyone else experienced headaches with aspartame?
