I don't think someone can just go from "I believe in God to I don't believe in him". Once you leave deism behind (because that's who you probably qualify as) you will most likely become agnostic (maybe there is a God, maybe there isn't) rather than atheist. I recommend watching Atheist Experience and debates between atheists and theists. My advice to you would be to take time. It'll probably take you a few years to consider yourself an atheist.
