What is this personality split I'm feeling since practicing Vipassana?

Ever since I've started practicing Vipassana, I'm starting to feel two distinct and diametrically opposite intentions are developing within me. The first one says "I've suffered enough, not any more! I'm prepared to do anything to experience Nirvana. Enough of supporting these cravings and desires, they have only lead to great suffering. I don't want to take another birth." Au contraire, the second one says "I want to enjoy the basic things in life. Though I've undergone a lot of sufferings, I should enjoy at least a little before leaving this world, its only fair. Is it wrong to enjoy things?" Whilst I vaguely used to feel this divide since long, its only since I've started practicing Vipassana that it has become more pronounced. Its as if like a big *battle* is going on between these two **forces**, and I'm just a spectator. Is this feeling normal, or my case is any different?
