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.

58 years old, retired due to disability, married 33 years, father of three, grandfather of four, Suffered a serious concussion at 10 years old (1965) stopped most driving after last concussion at 46 years old (2001), Post Concussion Syndrome/Multiple Concussion/Impact Syndrome with PTSD, immediate and short term visual and auditory memory problems, slowed processing speed, visual and auditory processing difficulties, insomnia, absence seizures, OCD, 14 concussions since first concussion at 8 years old, Taking paroxetine for 14 years and gabapentin for 12 years. Added L-Tryptophan and successfully stopped all paroxetine after 3 months of tapering down. I currently take 500 mgs of L-Tryptophan when I wake up, 500 mgs after breakfast with my vitamin regimen and 500 mgs late in the evening.
As of Nov 15th, Due to high stress issues resulting in PTSD, my docs put me on three meds. Clonazepam (Klonopin, a dreaded benzo but only for 30 days ) .125 mgs twice daily (Doc prescribed .25 mgs twice daily but half a tablet is doing good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic before bed. I have lost over 30 pounds since mid July. The olanzapine is supposed to help me gain some of it back but it has just stopped the weight loss. They took me off the gabapentin. I am feeling better than I have in years.
I am also taking L-Theanine to help with GABA regulation
