I’m in my 70s. About six months ago, I became ill and was extremely exhausted for nearly two months. I had a lot of phlegm, difficulty breathing, and was sleeping only two to three hours a night. Despite seeing doctors, no clear cause was identified.
Eventually, I was able to resolve the phlegm and breathing problems, but I still cannot sleep for more than two to three hours a night. I have not been able to determine what is causing the persistent insomnia or find a solution.
