I am so sorry to hear you are not sleeping. Like Lara, I can totally relate. I am not familiar with the meds you have mentioned, but I wanted to suggest a few questions to think about before you chat with your doctor...
1) Are you having trouble FALLING to sleep, or just STAYING asleep, or both?
2) Is the problem general sleeplessness, or is pain causing you to wake up or keeping you from finding a position you can sleep in?
3) Have you tried keeping a diary of your meals/beverages/activities in the late evenings to see if there are things you are doing that might be interfering with your sleep?
You may have already considered these things, so forgive me if they are not helpful. I am just suggesting them because they are the questions my doctors have asked me when I've asked for help with the sleeping issue. In my case, my back pain makes it very difficult to stay in one position very long, so I have a hard time falling asleep, and then if I move wrong the pain wakes me up in the night suddenly as well. So for me, the best way to get more sleep would be to improve pain control over night. This is still a problem b/c I don't really have adequate pain control ever, but knowing this has helped me know that I need to make sure I take one dose of my PRN pain meds about 30 minutes before I go to bed. On most nights, that lets me get to sleep pretty well and gets me through at least 3-4 hours before the pain wakes me up again.
I did have a doc prescribe a sleeping med once, but it didn't do anything at all for me b/c sleepiness was not really the issue. If you can nail down what the issue is, that may help your doctors find a med combo (or a behavioral change - like taking caffeine out of your diet) that would help better than what you have now.
I hope you can get in to see your doctor soon. Congratulations on a year of marriage, Kara. I hope you and your husband were able to take some time to celebrate.
