In reply to ladyjane85 who wrote - I do not have as much pain at night anymore, but often have
insomnia from RLS. I use melatonin and valerian root (supplements) and
occasionally an o/c PM med. But I can still have a no sleep night for no
reason, or only 3 to 4 hours. Gabapentin makes me drowsy all day with no
pain relief.

I am fortunate that my insomnia was unrelated to RLS or even pain (that developed after the insomnia, but became a major contributor to the insomnia). I don't take the Gabapentin for sleep, but i agree with you about the side effect of daytime drowsiness. I have often taken a nap during the day as a result, but try to limit them to mornings if I can. For my sleep I have found temazepam to be really helpful. It causes me to go into a state of relaxation in which I simply stop moving. It sounds really odd, but if I don't happen to get into bed in time sometimes I will fall asleep while reading and wake up at midnight or later when my clock strikes, only to find that my head has not nodded off and I am still holding the open book. Then I go into slow mo to get to bed.

The bottom line, as my sleep doc told me, is that there are a lot of drugs for insomnia out there. He started me on his plan A nine years ago and it is still working. So, keep trying and hoping that something will work for you.
