Cocaine is a psychological addiction not a physical addiction. Or, so I have been told by doctors I work with. Based on this, I think you need to get help right away. You have something underlying that is drawing you to the coke. There are medications out there that can help to free you from this. You need to find a psychiatrist (a good one who will actually listen to your plight) tell them everything and how much you are doing a day, and the anxiety that leads you to do it, and a good doctor will get you on a treatment plan which will help you eliminate your cravings for cocaine. Be honest, firm and demand help.
It's kind of slow on here this time of night. Make sure you bookmark this page and check back in tomorrow.
I personally don't know anything about coke but there are a few on here that can help you. Gizzy is one member that can help you so much. He is now over 5 months clean and gives some amazing advice. I'm sure he will be on here tomorrow to help you with anything he can. This forum has helped so many people with there addiction. Everyone on here is truly amazing! Please stick around and you will see what I mean! Best of luck to you!
