Those are strong eough to make you lose track of things, make you sleepy, etc. You probably need to bring a witness with you who can testify that when you are on your pain medication, which is needed to even get around, then you can't take care of your checkbook, interact with them, buy groceries, etc. because it makes you too "loopy". That kind of testimony means you couldn't work as a "ticket taker who sits and takes tickets" which is the most common job the SSA says you can do with a back injury.
If your doctor will write a letter stating that you can't do anything that requires arithmetic, meeting or providing directions to people, etc. then that would be very helpful to you as well.
Also, the judge may ask you if you can get a gall on of milk in the grocery store and put it in your basket the best answer is no, it's too heavy. A gallon of milk weighs the amount to make you able to do "light work".
Also, there is a website at www.lessonsinlaw.com that produces a number of books called The Guerrilla Guides to the Law. They are working on one right now on Social Security and when it is published you will want to get it because it will have all kinds of insider tips you can use to get approved. If you will go to that website and email them then they will send you an email when it is released. Most of their books are e-books and under $15 and my customers here seem to like them a lot.
