mowed over in the greek yogurt aisle

I've been trying to eat healthier lately.  More fruits and veggies, less processed carbs...it's not fun.  Never been a yogurt eater, but this greek stuff is tolerable.  You gotta be on your toes when you buy it, though.  I thought I'd read some labels the first time I got some, but hoards of women with flailing arms swarmed in from both sides and snatched them away greedily.  So I scooped some into the cart and ran away.  I keep hearing that a cup or two of coffee helps prevent lots of icky conditions, so how hard is it to start a coffee habit?  And wine in moderation is a friend of the circulatory system, so I could try to drink more than 4 or 5 glasses a year.  I'd rather drink pop and eat donuts, though.
