Amitriptyline is primarily an antidepressant, and it's very common for them to cause drowsiness, but there doesn't seem to be many studies as to how well they help maintain sleep, which would probably be key to my issue.
It's good that Amitriptyline is able to help you with spasms, though!
It's quite commonly used off-label for sleep at doses below it's antidepressant dose.
Yeah the medication has been incredible at managing my issues, I only take the full dose at of gabapentin at night though as I find it makes me 'wooly' headed if I take it during the day.
I've slept better since I've been taking the amytrypline though it wasn't taken for insomnia (which I've had since I was 17).
