I've been using coke on average once a week for the past 4 months consuming 0.5-1g each session. 7 days ago I turned 21 and went all out with 1.5g of good quality coke, I had 0.5 each night for 3 days (missing a day inbetween the 2nd and 3rd day) I was drinking heavily each time. On the 3rd day I felt as if I was going to have a heart attack at the end of the session and had to call an ambulance! The paramedics called me dumb as I am for going in so heavy and they said all was clear health wise. I've been asked to go out again this weekend clubbing and will more then likely be having 0.5 of the good stuff. It really frighted me when I had the bad experience and I was wondering if its safe for me to go out again tonight, anyone got any advice on what I should do? Nobody found out about this incident and I've got no plans to tell anyone, thanks!
