Just thought I would post this because I can't be ht eonly person going through stuff like this: I have FM and one of my problems is sleep. I have been taking Ambien for about 8 months, and have switched onto Lunesta and back off of it again 1 time when the Ambien has begun to lose effectiveness and I am back down to 2 hours of sleep per night. I typically take 30 days of Lunesta then do Ambien for 60 or more. So here I am, back to my routine of falling asleep at 4 am so I called to have the doctor's office switch the prescription so I can get some sleep. The receptionist called me back today to tell me that I cannot switch between the two medications in the future because it is too much work for the doctor's office to have to call the pharmacy back and switch it. Is it just me, or would having a patient sleep at night seem to be a little bit more important??? The receptionist told me that she does not think the insurance company will allow me to change medicines in the future, even with my doctor oking in. Is this a line of bull?
