I have been 15 days now without a spliff. This is from smoking green for four years but constantly for 2 years. I thought getting off the pot would make me better but my head feels worse than ever. Constantly worrying feeling like i am going to pass out a fast heart rate and feel horrible about everything. The last week has been worsre the first week was ok and felt fine. I was wondering how long it takes to get over this or is it all in my head some advice would be very greatfully recived.
