I have been drinking coke since I was about two and am addicted and drink enough to where it does not affect my ability to fall asleep.

I've seen that soda can help with attaining lucids, but was wondering if there is a level where it is just too much.

I have been having a little trouble with recall, and I started having trouble when I started buying cokes instead of just getting one a day with my school meal plan.

So does anyone know if it is just a coincidence or that too much of a good thing can be bad?
