my best friend is taking the medication ambien.
the problem is, she starts freaking out and it's almost like she's high off of it. she cannot remember anything the next morning after that, even talking on the phone for 3 hours with me. It scares me. she also becomes abusive when she's on them, like she'll punch me, or jump on me for no reason. sometimes she'll punch/kick a wall until she bleeds. and then she will tell me that she's glad i'm here, and to not leave her like this. i don't know what to do, and this medication was prescribed for her depression supposedly. Her doctor told her it would make her normal, but frankly it's doing the exact opposite.

please help me.
