Got Bog from Heinlein. I nice positive side effect of shedding mental handcuffs is that I restarted my sci-fi reading career, and being out for 20 years left me with a huge green pasture ;)

The exact opposite happened to me: I read a bunch of sci fi, and since very few of the authors I read were religious, I was essentially getting an atheistic worldview through books. That conflicted with my religious beliefs, and God lost.
