My roommate started a new job and she has anxiety issues as do I and I have been giving her a quarter of a 2 mg bar at bedtime to help her sleep. She only takes it every other night or so. She has only been doing this for a week. Will she go through withdrawals if she keeps taking the Xanax at bedtime and then tries to quit? I know that I am on 5mg a day and I would probably die if I quit but I will never be without some sort of benzo. I know it's illegal to share my script but she cannot sleep and she came to me and asked. I just don't want to hurt her in any way. She says the little 0.5mg helps her sleep and she wakes up calm and energized. Will she be able to quit without problems?
