I have insomnia as well, I think its pretty normal for us. I finally started a nighttime routine that I follow somewhat religiously.
It starts with no blue light an hour before bed. No cellphone, no t.v, no tablet. I make myself some sleepytime tea and grab a book, magazine,the mail something, sometimes I'll just cuddle with my hubby (he likes that one best)
Also i started working out in January, 25 lbs diwn,yay
So now come 10, my body is so done with the day.
In short, a nighttime routine will be your best friend

That's happened to to me as well, now and then, I have had 3 3/4 sleep and went to work in my years, the hrs varied but not much now, i have a good routine of prayer and bible study I have put together and that does help with that, I have a few times I'll be a little awake and such before bed, but, like I said my routine takes care of that, then I will get into bed and eventually get to sleep, 15 or 30 min I'll be awake maybe a little longer, but not much of a problem as for me, but has happened now and then.my opinion

Finding that comfortable place to sleep may help. I have only been sleeping for the last few months since someone gave me a recliner. I put the back into a comfortable position and the legs up. I watch tv and fall asleep. Since I have been sleeping, I can sometimes get in my bed and also fall asleep. i am not getting eight hours of sleep but a lot more than I was getting before,

Usually 4hr tho down to 2 now .I take lamictal now but have for more than 10yr.My neurologist told me she was recommending Hops tea to her pts now.(sleep loss must not be too unusual )Its helped me. It's a non caffeine herb.No meds!

Lack of sleep ladies is a big seizure problem! worst case scenario - ZZquil or some sleepy time tea!! - maybe both! Even talk to doc about a sleep med! I got some Trazadone - so strong I actually cut the pill in half - and it works!
