im sorry to hear about your loss.
I also taking tramadol and gabapentin. My pain is under control too but just like yours, my sleep is disturbed.
I have difficult to fall asleep, somedays i can sleep for more than 10 hours. It is very confuse, i have no time settled.
The last 6 months, i've notice the hours of sleep is decreasing, and i am now waiting for an appointment at Pain Management clinic, when i hope to get a solution for the problem. I will write to you about the outcome of this.
I would like to try a different medicine.
Tramadol and Gabapentin works for me in the last 4 years, but i always feel tired and restless, amongst with other side effects.
thank you for your post.
