I have been taking an ambien substitute to help me sleep for the past couple of months. I have gotten myself down to a quarter of a pill or less, but I am afraid of trying to sleep with out it...I have cut out caffeine past noon. But I have slept without the ambien pill I few times...and I didn't get enough sleep. Any suggestions? Meditation and deep breathing doesn't seem to help. I have some all natural sleep meds I just bought and have built up an immunity to melatonin so that probably won't help.
