Im going through the same mate. But im lapsing every few week.
And a few times this year i have gone a month or 2 with out
1st u need to delete all dealers nums out your phone, even friends and family.
Quit drinking all together as alcohol is a main trigger to get coke. Come off all social media.
Start new hobbies to replace your shitty routine. Take up decorating or the gym. Have some acheiveable goals.
Try some C.A meetings. Also i find listening to cocaine recovery stories on you tube help.
But i strongly recommend watching louise clarke on you tube. Her videos on crack cocaine part 123. Shes a quailfied expert and helps u understand why we get addicted and how to quit.
But you really need do put the effort in.
