I am a crack addict too...lol...
I usually need to do it right before bed and my partner gets furious but i tell him I HAVE TO DO IT...otherwise my bones will fidget and I just cannot be STILL...
I crack EVERYTHING my TOES my KNEES my ELBOWS my ANKLES all my FINGERS my KNECK my JAW my BACK absolutely everything.
I read that it doesn't do anything to you but my mom says I will be ARthritic soon because of it....i don't know I try to stop but I can't stand the Withdrawal symptoms...lol
