Are There Different Varieties Of Chantix Available?

I just started on Chantix 1.5 weeks ago. Taking 2 blue tablets (2mg) is too much for me. I remember last time I was on Chantix, I would take 3 white tablets (1.5) a day. I have 2 questions. The first one, can I cut the blue ones in half? The second one, do I need to be consistent by taking .5 in the morning, .5 at noon, then .5 in the evening or can I take a blue one in the morning and a white one at night?
