I have tried Imuran and the other drug for mg. They started affecting my liver so he said for me to try this drug, Methotrexate. Do you think this is too much to be taking. I realize this is a type of chemo drug. I was diagnosed with sleep apnea 10 years ago. I went from a cap then later needed a bipap. This past year, I felt poorly decided to go to have another sleep study done. This Dr told me I did not have enough apnea to use a machine. I went and had a second study done and he said the same thing. Thanks for trying to help. I don't feel like I have a good neuro but they tell me he is supposed to be a specialist in MG
