Some of the consequences that I have started to experience are decreased vision, neuropathy in my legs and feet, dka, abnormal heart beat, and chronic infections, the last one that I had in august spread so quickly that I had blood poisioning in a matter of hours and spent 9 days in icu. I had to have a port put into my chest with a tube that went into my heart so that after I left the hospital I could have iv antibiotics 3 times a day for 6 weeks. It was not fun. Telling you this in writing may not seem like a big deal, but it is! No one as young as you and I should have a port sticking out of them and a visiting nurse coming to see them everyday after work. Also, think of the costs. I have insurance but if I had not, I would be in the hole for $180,000 for the cost of that hospital stay.
I am not preaching because I still practice the behavior daily, I just don't want to se others go through the same thing. It starts out exciting because you lose weight so quickly, it feels like a high, but as the years go on it becomes an addiction. Sometimes you don't even want to do it but you feel almost obligated.
As far as how long I have gone without insulin, years at a time, it is a miracle that I am still alive. I have been in in-patient treatment for this eating disorder along with bulimia 3 times. I have been told that if I continue this behavior, there is no doubt that I will die a very early death, and it will be long, and painful with lots of suffering. Maybe you should think about that.
