You are headed for some serious health issues. You say you know them but you may not know them all. You should really talk to a doctor about what you are doing before it goes too far.
Right now, it might not seem so bad. It may help you feel better and feel like it's exactly what you need but I urge you not to give in to those feelings. If you continue this pattern, you will become very sick. You will most likely be hospitalized several times because it can kill you. If you don't stop now, when you want to stop, which you will probably want to do in the future, you won't be able to because your body will have become accustomed to the routine and will do it automatically.
The best way I know that you can find out how best to help you stop is to talk with a doctor, maybe even a counselor, too, to help keep you motivated. It's a good sign that you've realized this isn't something you should be doing. Keep strong and please seek out help before you end up being caught up in something that will threaten your life.
