I rarely sit down to have a shake. I shake up in the shaker jar with some crushed ice from the fridge and suck it down in a straw in a manner of seconds. The entire process takes about 2 minutes. Another thing you could do is prepare 2 in a small thermos before you leave and just drink some when you get a chance throughout the day. Straws really help. Can't say enough about straws.

Its really important you get those 3 shakes in early in the day. And its really important you get all of your MF meals in. The MF part of your food intake shouldn't be skipped.
Maybe this would be a good time to have a bar, instead, as well. Have your shake in the morning and bring a bar with you. You can nibble on it as you have time. (Be sure to drink water or something with it)
As for the salad, I believe its ok to have a small amount of other salad dressing. I know MF makes salad dressing packets, but I've never tried them. Personally, I don't care much for dressing, so I don't usually use it. Maybe switch it up and have the veggies from the list instead of salad?
I'd also consider picking up "Success in a Shaker Jar" it has a lot of good information in there that I didn't get from the doctor or the quickstart guide. It helps you understand how the program works so you can get the most from it and lose efficiently.
Good luck to you.
