liquid methadone what happens when you mix liquid methadone with xanax? I have seen people take the methadone pill with xanax before many times and they say not to do that . The other night we took liquid Methadone with xanax and I think my friend and I had a seizure. His a little worse than mine. He cant use his right arm. His whole body hurts. I think it was a seizure, I've had one before when I was detoxing. He hit his head right by his eye. He hit the back of his head also but when we tried to wake him up he wouldn't wake up , but he was snoring and all that was normal . I was just kinda worried about it , and thought you might be able to tell me something about it.
