A friend came to me and asked for help, she is a crack addict,( i think,) I made her move in with me to get rid of her friends, about 20 miles away.The first day she was very sick no food stayed down. Now the second day she has eaten some small foods and stayed down, she has slept most of the time. What should I look for or do now? How long will she be sick can she get over it with no medicine?
