I am just getting over a bad case of acute bronchitis. My doc prescribed 1mg Lorazepam for anxiety and insomnia. Now, 1 month later I stopped taking it 2 days ago. Having withdrawal symptoms worst of which is extreme dry mouth. Chest is also achy and burning, which may be bronchitis. Should I go back on it and taper off? Last took just 1/4 of the 1mg but also added 3mg melotonin to sleep. Is that a good way to avoid withdrawal? I've slept 2 hrs in the last 2 days.
