Dan is right, alcohol is a huge no if youre a cocaine addict – and an addcit dont have to mean you do it everyday, if you do it once a week youre addicted, I think you need to go get support from your doctor and your loved ones need to support you.
its hard to get away from it, but it doesnt end well. it all goes 1 way, read through some posts on here – there is lots of amazing advice, i would recommend addiction counselling its about 60 per session, once a week and believe me if youre dedicated it works, its all about reprogramming your brain.
you need to avoid alcohol, pubs, friends that do it – its hard but if you want to give up and stop you need to or this will repeat itself.
good luck and seek help before it gets even worse, xx
