Another thing, don't get stressed because you cant find a good milk/yogurt equivalent - you wont find one.
I tend to disagree. I used to be a big dairy fan

before I realised that milk means death for baby cows
For a while I thought that I was doomed to hate soy milk and other not-quite-right products, but then I realised that a lot of the dairy substitutes are really different from brand to brand. I recommend trying out whatever you can get your hands on and seeing which you like best. It's well worth the effort!
Whilst not all products are fabulous, some 'substitutes' are not in any way 'second-best' to their dairy counterparts! Here are my fave:
Tofutti better than cream cheese = Philly cream cheese minus the cruelty
Vitasoy Soy Milky Lite = Trim dairy milk minus the cruelty (at least how I remember it!)
Kingland yoghurts = just like dairy fruit yoghurts
Tofutti sour cream = just like sour cream
Kingland mayo = just like mayonaise
Soyattoo cream = just like (no, BETTER THAN) dairy whipped cream!
That's just my opinion, but as I mentioned, I used to love dairy and drank milk by the glass (bleh). But with these great products I don't miss it AT ALL!
Hard cheese is a tough one and there are some reasonable substitutes like super melty Cheezley, but I'll admit it's not QUITE the same! We keep searching on that one....
