How long will the pain last?!

I also threw up alot on the first day and i was in alot of pain for the first 3 days, on the fourth day my drain got removed and i felt alot better, ont he 6th day i was instantly free of any pain. today i am 12 days post op and i feel like i never got surgery at all exept for the 17lbs i have lost . each day you will feel a little better but i would say by monday you will feel new again and you will be able to sleep much better.
