Hi, my girlfriend has been getting Zanax off the street, and from what she says occasionally Methadone when she can't find Zanax. She has been acting very strange and she is starting to drive me crazy. Her symptoms include: Swelling of hands and feet, constantly chewing ice, and mint life savers, nodding out. Eating a lot of ice cream, wheezing when she breathes, nodding (but says she is just tired), irritable, always leaving the house, and sometimes full of energy where she cannot sit still. She has been hanging out with crack heads too so she may be doing that as well. My question is this: Do I need to just leave her alone? Will she ever be able to be sober again? Right now she says she doesn't have a problem, but she is driving me crazy with her new behaviors. Also, does anyone have any idea what drugs these are that she is on? She says Zanax, but I think it is more then Zanax.
