Hey
Donnie. Im not sure waht Bontril is, but I know she should not stop the xanax 'cold turkey'.. that needs to be tapered. As far as the hydrocodone, she should be safe stopping cold turkey.. keep her hydrated, well fed. She will feel sick for about 5 days - flu like symptoms (aches, pains, runny nose, restless legs, hot/cold flashes, sweating, stomach problems) and then start to feel better...
