I wholeheartedly agree with nightnurse. Try just the gabapentin. Your dose is very low so you may not notice a lot of difference. You should take it an hour or more before going to bed.
You also need to practice good sleep hygiene. Shut off those stimulating events around you. TV, loud music, etc. You might try some simple reading before lights out. The goal is to get your mind off the activities of the day and evening.
I need to start shutting my body down hours before I try to go to sleep. When I add the gabapentin to this more relaxed body and brain, it allows me to finish relaxing and letting go. It does not cause the sleepiness. It just allows it.
The Cyclobenzaprine [Flexeril] is also not a cause of sleep. It should just make your body more relaxed so you can sleep. It sounds like the gabapentin alone, maybe at an increased dose for bed, may do all that you need.
My best to you.

Added L-Tryptophan and stopped paroxetine after 3 months of tapering. I currently take 500 mgs of L-Tryptophan AM, 500 mgs noon, and 500 mgs PM.
As of Nov 15th, Due to high stress issues resulting in PTSD, docs put me on 3 meds. Clonazepam but only for 30 days ) .125 mgs twice daily (Doc presc. .25 mgs 2x daily but half a tablet is good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic that usually causes weight gain before bed. I lost over 30 pounds since mid July. It just stopped the weight loss. Took me off the gabapentin. I am feeling better than I have in years.
This great feeling only lasted a month. Back to the same old PCS doldrums.
May 2014, I am off the olanzapine due to a 6 fold price increase. Back on 600 mgs of gabapentin before bed.
I am also taking L-Theanine to help with GABA regulation
