Hi Josh,
I was up until 3 am yesterday so I know what you mean. I enjoy being by myself, that is why I often stay up late. If I am with people all the time for a few days I think I will go crazy, my skin starts to crawl. I really like being alone to read a book, watch a show, or go online.
If you want something easy and cheap, go to the store. Buy some generic brand Benadryl. You can ask the pharmacist which one. Store brand is usually right next to the Benadryl. I get the gel caps. You just take two about an hour before you want to sleep (say you want to sleep at midnight, take it around 11 or 11:30) and it will help you sleep. That way you can have more energy in the day.
