Hey Taz,
I have to emphasize how important Dennis' comment on the water is. It's benefits are incredible - from your synovial fluids, to digestion process, to skin ... pretty much every function.
Ensure is good and so is Carnation Instant Breakfast. They provide vitamins also. Lots of starchy foods (i.e. potatoes and bread). The whole grain variety bread is the best for you and it can't say just whole wheat- make sure it says whole grain. Sweet Potatoes are great because they are high in vitamins as well.
Most of all, stress is awful for your body so do whatever you need to to relieve the sources and be true to your needs. Positivity works wonders in all aspects.
