I actually think you have described it perfectly Capriciousness.

Mania will seduce you and make you chase dreams. We'll be the life and soul for everyone around us. Flights of ideas turn into unwise investments which seem perfect at the time. I won't lie, if I could be a little hypomanic all of my life, my, all the things I could do.

The problem is that it is not a sustainable mood and things get unpleasant so fast. Suddenly everyone bugs you, the only way you can stop the thoughts racing in your head is to drink or worse until you're in the gutter. There's always going to be that crash and burn that puts us in a pit of despair for months at a time. Where you just need a reason to breathe.

It's not worth the misery that it causes others or that it leaves you in. Be honest to yourself and those around you who care for you, even when you can't look after yourself.
