I m have anxiety problems and I m taking xanax .5 mg, 3 times a day. Due to a lot of stress taking care of my spouse who has alzheimer s disease, I am now unable to sleep at night. A few years ago, my doctor prescribed me some Restoril as a sleeping pill but last week the doctor that I saw at a walking clinic prescribed me some Zopiclone, because she said that it was not recommended to take Restoril and Xanax together. My mouth has been very dry since I started Zopiclone, while I didn t have any side effects when I was taking Restoril. Is it true that I shouldn t take Xanax & Restoril together even if I do not take them at the same time? Thank you.
