I have been taking xanax for years for terrible insomnia. I have taken 2 mg of xanax every night at bedtime and it helps me sleep through the night. Initially, my doctor tried every sleeping pill for me but xanax nothing else worked. So I've been taking xanax for years and it has always worked. I have always taken the blue football shaped pill UNTIL my last refill 5 days ago. I was given.the green 1 mg football shaped xanax. I haven't slept in days! Why is this? I wouldn't think the color would have anything to do with it. My question is how do I tell my doctor this and get my trustworthy blue xanax back? And why do the green ones not work?
