Boozer, ya it really does suck at first. My hardest thing was giving up coca-cola for diet coke. Now I've gotten to the point I can't stand the taste of real coke any more. I didn't give up coffee, and still lost weight. Don't want to encourage you to get off the wagon so to speak, though. Some changes you can expect, within a couple of weeks or sooner, you should start feeling more energetic. I noticed my hair (what little I have left) grew faster, so did my finger nails. The best part is after a couple of months noticing how loose your clothes are, it was cool to go buy new clothes in the same size I wore in high school. Keep it up dude, you will be glad you did.
