Aoi, you sound a lot like me.  I have lost a good deal of weight in the last year as well, and I have a high metabolism, and little food as well.  I am very much a meat eater when I can afford it though.  

Heh.  Soda...  Didn't know that anyone actually used that term for carbonated beverages.  

I drink a lot of pop when I have money, but when I don't, I drink about 2 gallons of water every day, and a whole lot of ramen.
Currently my diet consists of dry Corn Flakes, rationed hot dogs, and as much ramen as I can stomach in a day.  The ramen is starting to be rejected by my body though, so that's not a good sign.  I might have to find something else that's just as cheap soon.  Whenever I taste the stuff lately, I feel like I am going to be sick.  Ah well.  What can you do.  I get paid soon, so I should be able to buy some more crap.  I won't make rent this month anyways, so why not?  

  But like I said, survival is more than enough for me right now.  I don't care about my health.  In fact, I am sure that I will be buying a pack of cigarettes just as soon as I stabilize my finances.  

  I was thinking about hitting the food bank later on today though, so I might be able to get some real food.
