You think this is bad? You should have seen how Yuuna treated me when we were in university together. She'd forcibly lift me out of the library and take me to eat when there was a test coming up.

As for my recommendation, cherries have a natural chemical to help with sleep, and meditation can clear the mind. Yoga and light stretching before bed would help relax and loosen the body. Aromatherapy is also quite affective and scents like lavender have proven effective in assisting in sleep. These are all natural means, of course, there are chemical induced ones from sleeping agents, if it becomes bad enough.
