Yes I had applied and it took me 3 1/2 years to get it and was denied 2 times and then in front of the ADA Judged I had a major attack but yes I did have lawyer with me, but for me it was a long process and I even know of some that have taken longer and ended up quiting to get it but for some they got it right off the bat.
But there is a site somewhere under SSD that tells you how to apply with the do's and don't when applying for SSD I just don't recall the sites name but there.
Cowboy up
