Just have a few questions about something im curious of. i've noticed dizzyness, weakness, a bit of shaking in my hands, tar stool, nausea. when i ate a small amount of food it hurt to process after about half an hour or less. i believe i could have some internal bleeding occuring. i have the melena or whatever is best to call it. i can't find anything on the internet about how long i can hold off going to a doctor before this could potentially become fatal, so i was wondering a time frame of how long i can stay in bed and be okay. i would also like to know if it's possible for me to die in my sleep the longer i hold off going into icu. thanks -k
