How long does it take to completely get over a crack cocaine addiction? i used for eight months and have been clean for 35 days now.

Congratulation: congratulation,you are already a winner since you took the first step toward your addiction. addiction is a tricky thing usually they tell you that you will always be vulnerable,never under estimate the power of drugs,alcohol,smoking. so you are already 35 days clean keep going into this path ,and never consider yourself immune from the drugs because you have been clean for 35 days,

Physical and mental: There is the physical dependency and the mental addiction. Congrats on 35 days. Keep that up and work on watching for the mental behaviour of addiction - seeking it, thinking of it etc.
