Have you read Breaking the Vicious Cycle yet? If not, you can download a pdf of it at http://www.scribd.com/doc/11844050/Breaking-the-Vicious-Cycle-by-the-late-Elaine-Gottschall# . It's easy to make mistakes at the beginning, so don't get discouraged.
You need to make your own yogurt, because store bought isn't fermented long enough and still has a lot of lactose in it. You can use the stuff you bought as a starter, so long as it only has L. Bulgarius, S. Thermophilus, and L. Acidophilus in it (and no additives). Also, make sure you don't eat the bananas until they have lots of brown spots on them. Be wary of the strawberries, a lot of people can't do raw fruit at the beginning, and the seeds could be an issue too.
As far as money goes, I don't find it any more costly than a regular diet. I don't eat almond flour though, which is probably what people find to be expensive.
In the beginning, easy stuff to eat at work would be the yogurt, banana, and soup (or just the broth). If you make bone broth, that's supposed to be nourishing and would be easy to drink if you're not feeling well. Applesauce might go over well too.
