Hi, I'm just new to this group. I'm 39 and was diagnosed a few weeks ago. I started 15 mg of methotrexate today, due to increase to 20 mg in 2 months. I felt nauseous after a few hours but wasn't sick. Has anyone been really sick on these? and if so how often on a dose of 15mg weekly? I take folic acid 2 days before these. Also being female, 39 and in an early relationship I'm really worried about losing my hair.
