cocaine is an addiction just like everything else,as far as w/d i myself have never experienced cocaine w/d but i am sure there are some people here who can helpyou with that all i do know is the only way your friend will get clean is if he really wants to,no matter how much you want it for him he has to want it for himself but being in Al-Anon you are well aware of that i hope he knows how lucky he is to have a friend like you who seems to care so much good luck to both of you and keep posting there are really good people here and a lot of support you have come to the right place
hi and welcome to the forum....as far as physical w/ds there are not any. the mental part is a beast. i was on coke heavily for 5 years and now have 5 years clean...it was 3 months or so before i could function without thinking of using...i had used everyday all day and night....i slept for the first week...and gained 30 lbs the first month...you literally destroy your body on that cr@p. i was irratable and did not want to go anywhere or do anything for about 6 weeks. i would really suggest some type of aftercare....coke has a very high rate of relapse....i myself had a support group in my church i met with 2 times a week and attended some NA meetings as well as church...he can do it...in my journals i have a cravings list...its things you can do to stop the cravings before they become full blown...also i have a poem about coke print it for your frien. good luck, if i can help you or him please let me know.
