I accidentally took 180MG of morphine extended release tablets (my mom put her pills in a tylenol bottle without my knowledge). I don't know if this is a high enough dose to be dangerous. I never took morphine before and my breathing is becoming slow and shallow. Should I go to the ER. Would they be able to do anything for me? I don't have any health insurance so should I wait it out. I'm avoiding sleep since I think going to sleep isn't the safest idea. I normally don't take pain killers. The strongest thing I've taken is Vicodin after dental surgery so I suppose I have a low tolerance. My height and weight may matter, so I'm 5 foot flat and I weigh 170 pounds (I know I'm very overweight, but I'm working on it). I'm 19, if that matters, too. My mentality seems to be normal, I'm just tired and a bit dizzy.
