Im same as u michelle and im lapsing once every 3 week. Again its at the weekend. There is no way on earth you are going to go your mates and watch them use and drink without doing it yourself. Its impossible. So you either cut your mates off when they are using or dont. It sends me on the worse downer ever coming off coke. It takes me about 3 days to fully recover.
U need to cut everyone off to do with coke tbh. Why do you want to quit?
