Gaining

I gained 10 pounds!

Never "crash" gain. It has about the same fail rate as crash dieting. If you want to speed up your gain, it's best to push yourself just a little at each meal. See where you can fit in snacks and whatnot.

I gained 10 pounds!

Definitely true, but don't think you can't enjoy a good gorging every once in a while. I generally gorge at least once a week.

I just love the feeling of being super-full. Like almost to the point of pain.
