Hi Crazy Dingo,
You will find heaps of posts in here about appealing. I suppose it depends what they pick up in the medical. For example my husband was on Lipitor for high cholesterol so in order for him to be deemed fit he had to be without medication for 3 months and then get his blood tests done again. He also had to see a knee surgeon and nose surgeon as his nose has been broken.
Also because he was over 35? he had to have routine blood tests.
I thought the appeal process was actually quite fast once they received all the information - from memory it was a few weeks. His file is now at Tamworth and we are just waiting for a call..............
In the end I suppose it's about how bad you want it - there are many times when you question the process, time etc but it's all part of the journey.
I wish you the best of luck
Cheers
Liz
