Living off Ramen and Kimbap

After spending $313 on airline tickets for Hong Kong, I am now dirt poor. I have in my wallet $4, $38 in my bank and $163 in debt to my roommate. So for the next few days, possibly weeks and even month I will be living off Cheese Ramen and Kimbap (Korean type of rolled sushi with vegetables inside). Spending money here is very easy. Everything is so cheap so you want to buy it thinking it wont be much, but it all adds up. Food, drinking and little items. Plus the weekend trips to Seoul that cost $100 with nothing to show for it. Sigh, time to save.
