I was a serious caffeine addict on mountain dew for years.
I gave it up last year..only drink water, or sprite /diet sprite
Here's what happened
After the first week of major headaches ( withdrawl) I felt much better, more myself, no anxiety and on top of things
I lost 8 pounds the first month ( caffeine makes you retain fluids and all the sugar in Mt Dew was no good either )
I had major dental work because the years of Mt Dew ate the enamel off my teeth.
If I were one of those crazy law suit people, I'd sue the makers of Mt Dew for distributing the product with no warning about the effects of caffeine , it's addictiveness etc.
But....I'm just glad to be off the stuff
