The journey is nearly over now and I believe that I have noticed a few benefits to having done this. I used to have a lot of trouble sleeping, I would lay awake at night for at least an hour or so trying to fall asleep but unable to. Now when I lay down I'm out within minutes. I'm guessing this is because I no longer have caffeine in me preventing me from sleeping. But other than that I feel generally about the same as when I drank alot of Pepsi. I didn't know what to expect but I am just glad that the withdraw is over.
