All been said, but yes, expect it to be overload for the first few. As you get used to it, you'll start to enjoy a lot more.
It should become fun a lot sooner than solo; Personally now I've got a few hours past the 'solo' kick, I actually enjoy it more having someone along - yes, 'even' being under instruction.
If you like caterhams and motorbikes, it'll become *really* fun when you discover that 45degrees is not a steep bank, and you can go way past that without the wings falling off (in a suitable aircraft of course!).
