Hi @julied838, I too am new to taking methotrexate injections and take 1 mg folic acid daily. I’ve had gas and bloating and bouts of uc coming back. I found some foods trigger or worsen the nausea such as corn and my beloved green tea latte with almond milk so for now I’ve given these foods up hoping things will calm down. Hang in there and keep searching for options for me the side affects are becoming less of a problem. The mouth sores, rinse with hot salt water morning and night. I hope this is somewhat helpful.
