my pdoc told me to take some time off the ambien, then go back on. I think she meant like a week, but even a couple of days wiil help. I just don't have any coffee (or just have one decaf only) so I make sure I can sleep without it. I don't know how old you are, but I am very sensitive to coffee and it will give me heart symptoms, but as soon as I go back to one cup (or one "grande") per day I am okay again. cannot do two grandes, two days in a row or it's palpitation city for me.
