Is it possible for me to get more than what the court has awarded me on my divorce?

In Cook County Circuit Court, I was awarded 50% of marital assets and maintenance. However, my soon to be ex husband is appealing this judgment and we are going to trial. I have not worked in my field in over 32 years. I do not have the required work skills and I am 60 years old with health problems, having problems with my lower back (scoliosis) and Type I diabetes. My husband’s lawyer claims he makes too much money and should not have to pay "50 cents on the dollar" and for me to live on the assets should be enough. I feel this is grossly unfair so we are going to trial. I raised four children and took care of a large home and did all the duties of a good wife. I attended all the business functions and supported my husband in his business. Our children are all grown so there is no support issue but I am concerned about my health, how I am going to live my lifestyle with my health issues? Is there any advice? I want this divorce over with it has been going on for a year and a half. We are doing a "second disclosure". My temporary maintenance is barely enough and I am afraid that my husband's lawyer will state, "Well she lived just fine on the temporary maintenance."
