Well done m8.
Why don't you set yourself a goal wieght loss. Then when you reach it. Reward is a trial flight or next lesson. The practical side of things have been said by G. But as most flying schools are driven by making money i am sure you will find someone out there willing to teach you.
For gawds sake don't turn this thread into another pink headset thread
but I for one will be more than willing to help with questions in your progress through the system.
