I’m not a doctor but I have these too. I have had them for a while. I thought they were related to my MS but I am starting to question that. Once again I say I am not a doctor but I do take baclofen but I also take another muscle relaxer called tizanidine. It helps me sleep better than baclofen. If I wake up I take a 2nd dose. As long as it has been 4 hours since my fist dose. I take this medication along with the baclofen but I have MS. You may only need one medication. This is just a suggestion. I hope it helps. Good luck.
