No matter what I do or how good my hair looks today, it will be squashed flat tomorrow morning when I wake up. It's even worse if I go to bed with wet hair. Sleeping on it just kills any curl for me.
You might try doing your shower routine in the morning some day when you don't have to be somewhere for a while and see what happens. You'll find information about scrunching out excess water with a t-shirt or similar material and "plopping" on this site. I don't necessarily plop every day but I definitely use a t-shirt to squeeze out water. If I don't do those things the water weight pulls out my curl.
