Oh man, can I ever relate to this! I have to take ambien every night and it will knock me out initially, but I tend to wake up with leg spasticity, burning, overheated etc. and then once I’m up I spend the rest of the night tossing and turning or stretching, or writing random emails at 3 am. I have a lot of problems with daytime fatigue, and I know if I could just get quality sleep on a consistent basis it would help me be more functional during the day. It really is very strange to be so exhausted but unable to rest.
Have you discussed changing your sleep aid with your doc? Also, if there is something else that is keeping you awake, i.e. pain, worry etc. addressing these issues might help you be able to sleep better. For example, I stopped taking baclofen at night for most of this week (a recent addition to my nightly meds anyhow), and kept waking up around 2-3 am with my usual leg issues . I finally went back on the baclofen last night, and I didn’t wake up until 5 am and then was able to drift off and sleep some more.
Another thought is to ask about a sleep study, as there might be other factors affecting your ability sleep and/or sleep quality that you aren’t even aware of (i.e. sleep apnea, periodic limb movement disorder etc). It really is amazing how much lack of sleep can affect us, and what a huge impact it can have on quality of life. There was this series on sleep that is pretty amazing. I’ll try and hunt around for the link to it and post it if I find it.
