I don't know that I really buy in to the whole "this is what our ancestors ate" basis for the paleo diet, however, a diet that is pretty much nothing but meat and vegetables certainly can't hurt.
I do believe the massive doses of sugar (in all its forms) we consume in our Western diets is probably an unhealthy level. Reducing the amount of bread in my diet made a SUBSTANTIAL impact. I've cut soda out completely as well as artificially sugary drinks. My coffee is taken black and tea is no longer sweet.
It seems extreme, but I've taken to appreciating sweets in an entirely different way. Everything tastes a lot more intense. For instance, a few weeks ago, my company catered a meal and only served coke's for drink. I figured it wouldn't mater much so I drank one. I nearly puked at how sweet it seemed.
I'd say give it a week. You'll find bread and grains the hardest to give up, mostly because as you'll quickly find out, there is grain in everything.
After that week or so is over, you don't miss it too much.

If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.
