Hi i feel I should write my experience with matrifen patch and Tizanidine a muscle relaxant. I was on matrifen for nearly a year before I started having sleeping problems ended up sleeping alot during the day and waking up and going to the loo at night.
Finally 3 years later i saw a sleep doc and had an overnight sleep study and found out I had central sleep apnea where your brain doesnt make an effort to breath while asleep so came off matrifen patch(fentanyl) and it had gone.
But because I had been put on tizanidine in the mean time I still had sleep probs but because sleep studies came up normal. I did not know it was tizanidine at the time because of course I had been taking matrifen at the same time. But two years later I was getting fed up with sleep probs plus hallucinations as well and decided to try coming off it After asking Drs. I completely came off it and dont have sleep probs or hallucinations now.
I was put on a massive dose of Oxycontin for years by my Dr. Been off it a while now, but I too was diagnosed with Central sleep apnoea which is the frightening one where your brain doesn't say wake up when you stop breathing. After my sleep study I would stop breathing around 80 x per hour per night.
This has now almost completely gone, but my problem now is due to all the Oxy over years, I have B12 deffinciey & Pernicious Anemia where I just cannot sleep for long at all.
Funny how I've not read anywhere where sleep apnoea can be associated with opiates but I think we now know different.
Glad you're sorted.
Take care 👍
Thanks well my sleep Dr was sure it was that and did test when i came off and I didnt have it. It is scarey to think your meds can di that though. Mind you if you read the side effects they are worse than having the illness.
