It works really well, but I take it everyday and am afraid it is an addiction. I cannot sleep without it.
If you want to stop taking the Xanax, you'll need to ask your doctor for a proper, and slow taper plan. You cannot just start cutting doses in half, and so forth. This is why a doctor should be the one giving the instructions, to minimize any withdrawal symptoms.
You will most likely experience some rebound insomnia, so discuss other alternatives with your doctor for that as well. If I may ask, why do you want to stop taking the Xanax now?
