Hi Becky,
I'm new here but I take gabapentin, along with zanaflex and ms contin. At one point, they upped my dosage of gabapentin pretty high and I was also struggling with insomnia at the time and was still working. For that short period, I had some sleepiness with it but, at a dose of 1200mg/day, I've done fine. I've been on that dosage for approximately 2 years now. I still struggle with nightly insomnia but the gabapentin does not lead to daytime sleepiness despite the lack of sleep. It may be important to note, also, that I no longer work and my activity has been drastically reduced, leading to less fatigue overall.
Aside from the short period of daytime sleepiness, I haven't had any side effects at all. I have more side effects from the zanaflex (24mg/day) in that it really dries my mouth out.
Edit: I guess I didn't mention how well it works. It helps quite a bit with the tingling/numbness in my hands and with what I call "electric shock" pains in my arms. I don't have "true migraines," but it does not help my headaches at all.
