So I'm new to this and I don't know what to think. I was told by the people around me that I had overdosed and came out of it. Pretty much woke up to being given CPR with ice on the back of my neck and my head propped up on a pillow. I don't remember anything after doing a shot of heroin and walking out of the bathroom. I was told that I had no pulse and was turning blue. My friend preformed CPR and I someone came too. The same thing happened one time before. My lips turned blue and I was unresponsive for about 15 minutes each time. I don't remember either time. I thought when people overdosed they died unless medication was given to being them out of it. I was addicted to black for a year and used about a gram and a half a day just to maintain being normal. I was locked up for 4 months went back out twice and both times using a b or less I've stopped breathing and had almost no pulse. But both times the people around me claimed I've come out of it. I just didn't think that was possible without medical attention. Any ideas on how this is possible? Should I just assume they are lying to me about it?
