I noticed that I was being pretty affected by Diet Pepsi. I was drinking at least 2 liters a day.
I drank Crystal Light at work for a week. I got headaches and dizziness. Finally I realized it was the Aspartame after not being able to drive. I stopped and the headaches stopped.
My girlfriend gets migraines. She stopped too, but the lithium weight gain is urging her to start again.
My best friend’s left ankle swells when he drinks it. (!)
The stuff is dangerous.
