I did over 10g of coke with my ex

After we broke up, he offered me to share half a kilo of coke with him. (For the record, I dont do coke, neither does he). I was around 7 months clean at the time and said yes. We had some drugs and I did 3 lines, and then I decided to drink. I drank so I was very, very drunk in the space of an hour, and thought i was fine, then I looked around and noticed how drunk I was, and the coke was straight infront of me. I did about 2-3g in those 3 hours, and close to 5-6g in the next 12. I was terrified at one point and had to call my partner, who told me to relax and that I would be fine. I had 2 hospital trips in the 48 hours I was there. I had to take 10 benzos to knock myself out. And i couldnt sleep the next night because my nose was too sore (it was bleeding for 4 out of the 5 days). I would say i did a total of 11g. I dont give any kind of drug advice but I would say over 10g is probably too much.
