Angel,
I also made a lot of shakes during my treatment, got some recipes from the hospital. I don't recall the exact ingredients but did include milk, ice cream, yogart, and ice (the cold sure felt good). I would also add Carnation Breakfast mix, whey protein powder, instant non fat milk, and various fruits for the added nutritional value.
My kids even enjoyed them, so I had to make extra each time!
Also, make sure you mention your vision problems to your doctor.
