I am feeling there is no hope because he says he will never take medicine.

I have been married to a man with ADD/ADHD for 14 years. He has taken medicine several times. In my eyes, the medicine was a miracle! I felt like I had a partner. I wasn't carrying the weight of our lives on my shoulders. He got off the medicine because he said it makes him feel dead inside. For 5 years I have held onto the hope that he would realize how much medicine helps him and maybe try a different medication. Currently our lives are suffering tremendously because of his untreated ADHD/ADD. I asked him if in an effort to help relieve some of the stress in our marriage he would please try some of the other medications out there. He said he won't. I am committed to my marriage but I am completely miserable. I am 3 months pregnant with our 4th child and he is unemployed again. He watches TV and the IPad for 10 hours a day. I am so alone in my marriage! I do almost everything myself. I am so scared that my kids are learning to be lazy by watching him. He has an issue that needs treatment. Why doesn't he see how important it is? He had only tried adderall. I researched many other medications and there are other options but he absolutely refuses to try anything else. Any ideas?
