Any recommendations for my condition psoriatic arthritis not to eat or drink and what can i do when i start the medicine methotrexate

Psoriasis and gut: Psoriasis is an autoimmune state. Autoimmune means your body is fighting itself. Why? Usually it is triggered by stress of some kind. Address this with managing stress cleaning the gut (probiotics and clean eating). Methotrexate is harsh on the liver so eat liver friendly diet like greens, cruciferous and lemon. Do breathing exercises when stressed. Address sleep issues.
