Hi, Debbie
My husband went off the pain meds cold turkey: this is not easy to do, and may have contributed to the insomnia as well. Using a humidifier helped with the dry mouth that help with sleeping.

It sounds like he is working on helping himself to get better with the protein drinks, gym time and spending time with you. As David mentioned, seeing a trained specialist is the routine to go if that little voice in the back of your head tells you to.

Hope the your day at the beach was pleasant!
