I am in the same boat as you, thought about distance learning, started distance learning, but with a full time job in IT, working weekends, nights, I was not getting anywhere.
I decided to take redundancy, I am lucky in that respect, I am due to start with CATS on the 8 Oct full time, One of the biggest reasons for going full time is due to wanting to have a good understanding of all the subjects, Its one thing to pass them, but when you are given a chance of an interview, you want to make the most of it. The ATPL theory will always come back at the interviews
Beeing in the company of other wannabes will also help keep motivated, as you won't get the feeling of being alone. I'm sure 6 months will go by very fast
