Are there any "at home" treatments or recommendations for addison's and graves disease? I also have other auto immune disorders.

Stay healthy. These are two serious endocrine diseases that need full dose conventional treatment as your backbone regimen. The addison can be controlled and its treatment sometimes help other autoimmune conditions as well. The graves can be cured. Please see your doctor to have regular checkup. Good luck.
Auto immune. No he remedies, you need to be under medical treatment with an ophthalmologist and either a rheumatologist or immunologist.
